BAR driver Jenson Button has spoken out to explain the thinking behind his controversial decision to leave the team next season to return to Williams.
Button was keen to explain his side of the story
He told ITV Formula One that he had intended to break the news to his team more tactfully but went public because of the story being leaked to the press.
"I told (team boss) David Richards through my manager," he said.
"Afterwards we were going to have a face to face meeting but so much got leaked, it made things difficult."
He also denied being greedy, and said the decision was down to the fact that he was ambitious and felt moving to Williams was the best way to increase his chances of becoming world champion.
"BAR are a great team and I've really enjoyed my time, but it's not like I've not worked hard for it.
"I've been giving my all, it's a big team effort, a lot of it's down to myself.
"I'm not greedy, though - I can say 100% that I'm not moving for the money," he insisted.
"We've had a good season, I'm not going to take anything away from the team, but for me Williams is a team of the future.
"I have to keep improving. Every year since 2001 has been a step forward, and next year I want to challenge for the championship. Williams is the team that gives me that possibility.
He admitted his close relationship with Richards had suffered, but said overall the team had been supportive despite their disappointment.
"We get on very well, our working relationship is still very good," he said.
"We have been friends off the circuit but I'm not sure if that will be the same in future - I hope it will be.
"It's nice to tell people the reasons for it and the ideas behind it.
"The team have been great without knowing my side of the story, a lot of them are supportive."
