The British Prime Minister, Mr Tony Blair, will share a platform in Belfast next week with the former prime minister, Mr John Major, in the push for a Yes vote on the Belfast Agreement.
With Mr Major expected to address the business community in Northern Ireland on Wednesday, it would allow Mr Blair the opportunity to urge support for the agreement.
Downing Street has indicated Mr Blair will make two visits to the North, with the first visit taking place alongside Mr Major and the second with the Tory leader, Mr William Hague, and the Liberal Democrat leader, Mr Paddy Ashdown.
