David Drummond, Google's Chief Legal officer reveals he was "shocked, surprised and outraged" by Edward Snowden's revelations that the NSA hacked the company's data.
Speaking exclusively to the BBC's Mishal Husain, Mr Drummond said: "I think that the government certainly needs to reform its practices. We work extraordinarily hard to protect our users and to ensure their trust."
Barcelona forward Lionel Messi is not for sale and the club plan to discuss a new contract with the Argentine, says president Josep Maria Bartomeu.
Four-time Ballon d'Or winner Messi, 26, is reported to be a target for French side Paris St-Germain.
In an interview with radio station RAC1, posted on Barcelona's website, Bartomeu said: "The club will sit down and negotiate a new contract.
"We will do what we have to, to ensure he's the best-paid player."
Messi scored 60 goals in 50 appearances last season, but has struggled to match that goalscoring form in 2013-14.
He has scored 18 goals so far but just eight of those have been in the league - with his last coming in September, before he was out for five weeks with a hamstring injury.
However, Messi has provided 36 assists in 20 appearances and Barca coach Gerardo Martino said: "He is a footballer that can do everything. If he succeeds in other facets of his game, it doesn't matter if he scores.
"Nothing surprises me with him. He controls the game well, passes the ball well, he is a good finisher, he can press and recover the ball.
"He sees passes that most people can only see whilst watching the game on TV or in the stands, not ones that you can normally see on the field."

Ninety-six fans died in the 1989 crush "Key police suspects" are expected to be interviewed ahead of new inquests into the victims of the Hillsborough tragedy, says the police watchdog.
The Independent Police Complaints Commission (IPCC) said it was beginning to focus on the individuals of "significant interest".
Ninety-six Liverpool fans died as a result of a crush during an FA Cup semi-final game, on 15 April 1989.
Fresh inquests into the deaths are set to begin on 31 March.
Ms Rachel Cerfontyne, deputy chair of the IPCC, said the inquiry was on track to provide information for the inquests, which are to be held at Birchwood Park.
"This has been a huge task, but we are on course to meet the deadlines set by Lord Justice Goldring," she said.
'Altered accounts'Almost all officers, whose accounts are suspected of being amended, have been interviewed, she explained.
Out of the officers whose Hillsborough accounts are suspected of being altered, 160 officers had already been interviewed and 32 would be interviewed before the inquests.
Of the remainder, 22 are dead, 12 have been deemed unfit for interview and 13 officers have declined to be interviewed, while two officers failed to respond to the IPCC's request to be interviewed.
More than 1600 have responded to the IPCC's witness appeal, 275 who have never previously given their account of the tragedy.
The IPCC said it was now widening its witness appeal and it was urgently seeking people who can help with the inquests.
It was originally launched to find out about people's experiences of dealing with West Midlands Police who gathered evidence for the original investigation into the disaster and subsequent inquiries and inquests.
Biggest investigationThe police watchdog revealed there were "differences" between fans' statements and questionnaires they returned to the West Midlands Police inquiry.
The IPCC's investigation is the biggest undertaken into police conduct in England and Wales.
It follows the report by the Hillsborough Independent Panel, published in September 2012, which concluded the lives of 41 fans could have been saved and cleared Liverpool supporters of any wrongdoing.
It found South Yorkshire Police had altered statements and tried to blame fans.
The original accidental death verdicts were then quashed in December 2012 at the High Court.
Seven men and one woman have been arrested in Newcastle on suspicion of conspiracy to rape.
Northumbria Police said 11 properties in the city had been searched as part of Operation Sanctuary.
A force spokesman said the inquiry involved allegations of sexual assault involving teenage girls and young women - some in the care of the local authority.
The city council said it was working with police to help alleged victims.
Council leader Nick Forbes said the authority was informed about the investigation a week ago and he was "shocked and appalled" by the allegations.
'Extremely serious'Temporary Assistant Chief Constable Gary Calvert said: "This is a sensitive investigation which is at a very early stage and moving rapidly.
"I understand that these types of allegations can cause the public concern and I want to reassure the community that police take crimes of this nature extremely seriously and will thoroughly investigate them.
"Our overarching priority is to protect any victims or potential victims and to bring any offenders to justice."
Mr Forbes said that those arrested were from various parts of the city.
"There is absolutely nothing to suggest the alleged offenders are from any one community - they are from a range of backgrounds, range of communities and range of areas of the city, but inevitably events like this do raise people's concerns", Mr Forbes said.
"But it is important to point out that the alleged victims and offenders were known to each other."
Graeme Swann said he chose to walk away during England's Ashes whitewash because his bowling was "awful" and he felt "powerless" during matches.
The spinner, who quit cricket after the third Test, described the decision as the "most sobering" of his life.
"It was a horrible feeling to come to terms with," Swann told Radio 5 live.
Swann also gave his backing to captain Alastair Cook, saying not even legendary skipper Mike Brearley could have turned around a failing team.
Swann, England's sixth highest Test wicket-taker with 255, caused a major shock when he announced his retirement from all forms of cricket four days before the fourth Ashes Test in Melbourne.
Speaking on 5 live's Not Just Cricket, which airs at 21:00 GMT on Monday, Swann said his performances in the first three Tests - he took seven wickets at an average of 80 - caused him to bring forward a departure he had planned for the end of the tour.
As the effects of a second elbow operation in March 2013 took their toll on his bowling, the one-time match-winner felt he had become a liability.
"Quite simply, I was awful," he said. "Whenever I bowled in the past, I could always get a lot of revolutions on the ball, dip and trouble most batsmen I bowled at.
"But from the outset of the tour, in the warm-up matches, I just couldn't do it. After my second elbow operation, I've never really got the same revolutions I got before it, but it just [deteriorated] and I really felt powerless to tie people down.
"In Adelaide, I was getting hit for six by a rabbit who bats at number 11. It gets to a point that you realise you are hindering the team. You are not helping them in any way.
"It's a horrible feeling to come to terms with because you are playing for your country, you love playing cricket for England and it's your life, but to actually come to that conclusion is possibly the most sobering decision I have ever had to make.
"It was horrendous."
The 5-0 whitewash in Australia was only the third in England's history and statistically their worst ever Ashes tour.
But Swann was quick to deflect criticism from Cook and described the dismal series as a collective failure.
"No man could have captained us this winter - there is not a captain on earth," he said. "You could bring back Mike Brearley and he wouldn't have done any good.
"We were terrible. We have got to get more improved performances from the team and then the captain will be able to do his job.
"Cook should keep doing the job he was doing beforehand, not panic about what has happened and just get everyone together and think how are we going to go about scoring big runs again.
"That is the only way you can win Test matches. It's what we did arguably for five years. We were so good because we had such a reliable top order who were scoring so many runs. If we can get back to that we will be fine."
The aftermath to England's disastrous Ashes campaign has featured claims of splits in the dressing-room.
Swann says the reports, including a rumoured rift between coach Andy Flower and star batsman Kevin Pietersen, have been wide of the mark.
"It will probably surprise people to hear that the changing-room was not divided," he added. "It was remarkably calm. People just knew we were not performing and they were doing whatever they could to improve that.
"Some of the stuff I have read is just a made-up pack of lies. There was one line in one of the famous tabloids saying KP refused to go to the Christmas dinner. He sat on the table next to me with his whole family.
"He's had his moments in the past where he certainly has been divisive in the dressing-room, but to be fair to Kev, since coming back from his 'reintegration' he has been much improved."
Australian Open champion Stanislas Wawrinka said he did not believe he was good enough to win a Grand Slam.
The Swiss, 28, beat world number one Rafael Nadal 6-3 6-2 3-6 6-3 in Sunday's final in Melbourne.
He is the first man outside the 'big four' of Nadal, Roger Federer, Novak Djokovic and Andy Murray to win a major since Juan Martin Del Potro in 2009.
"I never expected to win a Grand Slam because, for me, I was not good enough to beat those guys," said Wawrinka.
It is a measure of Wawrinka's achievement that, along with Del Potro, he is only the second man aside from the 'big four' to win one of the sport's major titles since Marat Safin at the 2005 Australian Open.
"To win a Slam, to be number three [in the rankings], both for me is a big surprise," said Wawrinka. "But I think more so to win a Slam, because in the ranking you can be number three without winning a Slam. But now both are happening, so it's a big surprise.
"It's an amazing feeling. I saw Roger winning so many Grand Slams in the past, so now it's my turn to win one.
"If you look at the 10 past years, except Del Potro, it's only the top four guys who were winning all the Grand Slams."
Wawrinka's success this week takes him past 17-time major winner Federer to become Swiss number one for the first time.
"Roger is a good friend," he said. "He's for me the best player ever. He's been there so many years.
"He was struggling a little bit last year, but he's an amazing player, amazing friend, because he always wants the best for me.
"He's always texting me. Even if he lost, like in the US Open [third round], he was the first person to text me before the match or after the match.
"I didn't call so many people, but my wife, my daughter, my sister, and Roger called me. So, yeah, it was nice for me.
"I know that he's really, really happy for me. He always wanted the best for me."
Wawrinka played superbly to lead by a set and a break in Sunday's final, before the match took a turn when Nadal received treatment for a medical timeout - something Wawrinka quizzed the umpire about.
"I just wanted to know what was the problem of Rafa," he said. "Because before he asked the physio, he was checking his feet. I didn't know really what was the problem.
"Normally when the physio is coming on the court, the umpire always tells the opponent why he's coming. He didn't want to tell me."
After moving two sets up, Wawrinka dropped the third and lost an early lead in the fourth as he struggled to put away an ailing opponent.
"I was surprised how well I started the match," he said. "In the beginning, he was good, he was fit, he wasn't injured. And myself, again, I was playing amazing tennis.
"Then there was the second match in the match. I had to stay calm with myself, just try to stay aggressive, because he was injured.
"But he was still trying a little bit. It was not easy. I started to be really nervous because I started to realise that I could win a Grand Slam.
"So it wasn't easy, but at the end I just came back to the game and focused on what I wanted to do."
