Tottenham have confirmed that Scott Parker has joined the club from West Ham.
Parker completed his switch on Wednesday, having handed in an official transfer request less than 24 hours earlier.
The former Newcastle, Chelsea and Charlton midfielder is currently on international duty with England and is expected to join up with his new team-mates after next week's Euro 2012 qualifier against Wales.
A statement on Spurs' official website said: "We are delighted to announce that we have reached agreement with West Ham United for the permanent transfer of Scott Parker."
Parker, 30, stated on Tuesday that he had asked to leave West Ham in order to maintain his position as a regular in the England squad.
"I need to be playing in the Premier League, especially now that I am involved with England," Parker said. "I hope the fans will understand and respect my decision and I wish the club every success in their fight for promotion this season."
West Ham also confirmed Parker's departure on their official wesbite, saying: "The club have reluctantly agreed to the transfer of Scott Parker to Tottenham Hotspur. "The midfielder has moved to White Hart Lane after handing in an official written transfer request on Tuesday night, despite the best attempts of the Board and management to retain his services.
"West Ham United would like to place on record their thanks for Scott's efforts and wish him well for the future."
