Ian Paisley and Gerry Adams today announced an historic agreement that will restore devolution to Northern Ireland in six weeks time.
The DUP and Sinn Fein leaders confirmed the deal in a joint Stormont press conference that would have been unthinkable a few months, if not weeks, ago.
Its significance was swiftly hailed by Prime Minister Tony Blair, who said: " This is a very important day for the people of Northern Ireland but also for the people and the history of these islands."
Mr Paisley and Mr Adams sat close to each other at a table, as they read out separate statements, flanked by party members.
The DUP leader said his party had "agreed with Sinn Fein" that devolution would return on Tuesday, May 8. Mr Adams said the agreement " shows the potential of what can now be achieved".
The two parties have asked the Government for a deferment of water charges and are also seeking another meeting with Chancellor of the Exchequer Gordon Brown on a financial package for the incoming power-sharing executive.
Today's deal led to Secretary of State Peter Hain dropping his March 26 deadline for the restoration of devolution.

The minister warns that if the main parties cannot find an agreed path back to devolution, direct rule by English, Welsh and Scottish ministers would be prolonged.
