Rishi Sunak has piled pressure on the Democratic Unionist Party (DUP) to get Northern Ireland's institutions up and running or risk harming the union.
The Prime Minister used a speech to mark the 25th anniversary of the Good Friday Agreement to praise political leaders for having courage "more powerful than a thousand bombs and bullets" to reach the landmark peace deal.
He said people on all sides "showed courage, imagination, and perseverance" to negotiate the agreement in 1998 which brought an end to decades of bloody conflict.
