Mayor of London Boris Johnson has donated a pair of his unworn underpants in order to raise money for Help for Heroes.

Listeners of LBC were invited to bid for the Mayor's personal, signed wristband along with the pants.

The bidding for the wristband and the underpants reached £205.

The Mayor described the charity as a "great cause" and vowed to sign the underpants for the lucky winner.
