Bruno Senna has confirmed that he has secured a Formula 1 deal for next season - with an announcement about his move to Campos Grand Prix expected imminently.
The Brazilian has been locked in negotiations with several teams about a deal for 2010, but there has been mounting speculation in Abu Dhabi that he finally signed a contract to join the new Campos team in the last few days.
Writing on his Twitter page on Friday night, Senna said that after weeks of pushing hard to land an F1 deal, he has finally realised his ambition.
"Guys, I'd like to thank you all for the great support! After many weeks of hard work and negotiations, me and my management finally made it," he wrote.
"I'm very happy and I'd like to share this moment with you! Now it's time to focus and work hard in preparation for next season!
"Lots of hard work to come and, hopefully a great starting point! All the best! Valeu!!"
Senna spent this season focusing on sportscars after failing to secure an F1 drive, but made no secret of the fact that his ambition was to get into grand prix racing as soon as possible.
It is not clear if his Campos deal will prevent him from testing for Renault after the season, having had discussions about a young driver day with the French car manufacturer.
