The Fortnum & Mason Charity Christmas Party is being run in partnership with theBigGive.org.uk.

The Big Give Christmas Challenge is your chance to have your charitable donation doubled, making it worth twice as much to your selected good cause.

The party will be a preview of the 2011 Challenge, which will launch on Monday 5th December. If you donate your £50 voucher during the Challenge week it could be worth twice as much.
