Prime Minister David Cameron has offered his congratulations to Europe's Ryder Cup team on their "stunning" victory.
Captain Colin Montgomerie's side triumphed by the tightest of margins, 14 1/2-13 1/2, at Celtic Manor as Graeme McDowell held his nerve to beat Hunter Mahan 3&1 in the final match of the event's extra day.
And Mr Cameron said: "Congratulations to Colin Montgomerie and the Europe team on a stunning Ryder Cup victory."
It was the first time the event had ever gone beyond its regular three-day distance, due to 13 hours being lost in the Welsh rain on Friday and Sunday.
"After a stormy weekend, we will long remember the drama of the first ever Ryder Cup Monday played in the Welsh sunshine," Mr Cameron continued.
"Well done also to the crowd at Celtic Manor who more than played their part."
