Writing in the Mail on Sunday, former Labour fundraiser Lord Levy said Mr Brown would drop his counters in a straight line and never see that his opponent had two on one side and one on the other so he could drop a winner in the middle.

"He got caught every time, and then sat there staring, with this big stupid look on his face as if to say 'how did that happen?'"

According to Levy, the then chancellor also lined up his battleships in exactly the same formation and failed to grasp the fundamental principles of Snakes and Ladders, insisting that if the underlying conditions were in place it would be possible to climb up a snake.

One Blair aide said: "Of course we used to move his pieces around every time he went to the loo, but he was so off the pace he never even noticed."

It is understood Mr Brown used to be good at Monopoly, but Blairites insist this was only because he inherited Bond Street and Regent Street from Ken Clarke.

The source added: "At one stage he even had Mayfair and Park Lane, but then he mortgaged them to buy votes in the Midlands."
