A top UK Government official called for a 'unique' one-off friendly match between Rangers and Celtic in Belfast.
The match was proposed by Alastair Campbell and was to be played to drum up support during the final days of the Good Friday Agreement referendum.
The released Cabinet document was uncovered less than a year ago and shows, an email from the former Downing Street director of communications writing to then Prime Minister, Tony Blair in April 1998. It was also suggested that the two sides swap each others jerseys as a gesture of unity and that this would be 'very powerful'.
