He joins Brian O’Driscoll, Jonathan Sexton and Jamie Heaslip, who also signed new deals at Leinster earlier this month, as the IRFU signals its intent to keep its star countrymen plying their trade in Ireland.

National team coach Kidney said: “The IRFU’s policy of keeping as many players in Ireland as possible is an important part to helping Irish Rugby challenge for success in competitions at all levels.

“The news that Mike has made the decision to carry on his career in Leinster is good news for everybody concerned as he has continued to progress well and is a valued member of the international squad.”

The prop, who has won seven caps for his country, has made 39 appearances for Leinster since moving from English premiership side Harlequins in 2009.

He said: “It’s been an enjoyable couple of months for me and I am delighted to be able to have my new contract agreed and to remain playing for Leinster.

“Since coming back to Ireland, Leinster really has become my home and hopefully I can continue to maintain my performance levels to help keep the team successful and also keep me in the frame for selection for the Ireland team.”
