Paris St-Germain have confirmed the signing of Yohan Cabaye from Newcastle.
The France midfielder has penned a three-and-a-half-year contract at the Parc des Princes.
The Ligue 1 champions said in a statement: "Paris St-Germain is delighted to announce the transfer of Yohan Cabaye to the capital club from Newcastle United until June 2017. He will wear the number four jersey."
PSG had a £14million bid for Cabaye rejected by the Magpies on Sunday but the French club have now secured the services of the 28-year-old.
Neither club have revealed the final price tag for Cabaye - with Newcastle announcing the sale for "an undisclosed fee" on their website - but reports in France on Wednesday suggest PSG have paid in the region of £20million.
Cabaye said of his move: "I was won over by the ambitious project at Paris St-Germain and I can't wait to join this exceptional squad and help the team reach its objectives in France and in Europe."
Cabaye will link up with the likes of Zlatan Ibrahimovic, Edinson Cavani and Thiago Silva at big-spending PSG, who last season were crowned French champions for the first time since 1994.
Managed by former France coach Laurent Blanc, PSG are also on course to retain their title this term as they currently boast a three-point lead over second-placed Monaco, with Lille 10 points back in third.
PSG are also through to the last 16 of the Champions League, where they will face Bayer Leverkusen in the first leg next month, and in the Coupe de la Ligue semi-finals.
Club president Nasser Al Khelaifi said they had beaten a number of top sides to Cabaye's signature.
He said: "Wanted by a number of prestigious clubs, the new Parisian midfielder has chosen to join Paris St-Germain.
"The transfer of Yohan Cabaye is further proof of the club's capacity to attract the best French and overseas players.
"We are exceptionally delighted to welcome him to the Paris St-Germain family to help in its upcoming challenges in the second half of the season."
