Northern Ireland's political leaders know the "right thing to do" and should "get on and do it", former Prime Minister Sir Tony Blair has said.
He was appearing alongside former US president Bill Clinton and ex-Taoiseach Bertie Ahern at a major conference in Belfast marking the 25th anniversary of the Good Friday Agreement.
Mr Clinton told how politicians "winged it" to help secure the historic peace deal in 1998, while Mr Ahern said he hoped the DUP would allow Stormont's power-sharing institutions to be restored.
