Chris Robshaw has committed his future to Harlequins after signing a contract extension to keep him at the Aviva Premiership side until the end of the 2015/16 season.
The back-row forward, who has captained England 16 times since the 2012 RBS 6 Nations campaign, will also continue as Quins skipper for the coming campaign.
Harlequins director of rugby, Conor O'Shea, said: "I think it would be an understatement to say that this is great news for the club and all of its supporters.
"Chris is not just an incredible rugby player, he is and has proven to be, one of the great leaders of the modern game.
"In appointing him as captain again for the forthcoming season and given his commitment to extending his stay at his club through until the end of the 2015/16 season we know we have a player and person who will do everything he can to lead this club to the success and levels we all crave.
"Chris leads on and off the pitch in a manner which is beyond question. I know his motivation for success with both Harlequins and England burns greater than ever."
Since being named Harlequins captain in 2010, Robshaw has led the side to becoming Premiership champions in 2012 and Amlin Challenge Cup winners in 2011. He was also named the Premiership's Player of the Year in 2011/12.
Robshaw said: "I am honoured to have committed to Harlequins to the end of the 2015/16 season. It's a fantastic club with huge aspirations, which I am excited to be a part of.
"I have learnt so much in my time here and continue to do so from all the people around me, including the coaches and players.
"I am really looking forward to kicking off this season and winning more silverware with this great club."
