The campaign which launched on the international day of giving (#GivingTuesday) offers to match any donation made to participating charities has already raised over £4 million to hundreds of participating charities.

Celebrities like David Tennant, Professor Green and Davina McCall have released videos in support of charities which are participating in the campaign.

Thanks to many celebrities sharing the campaign through social media, the #ChristmasChallenge18 trended on Twitter most of Tuesday afternoon. There are over 500 charities participating in the campaign, raising money for a wide variety of causes including mental health, environmental issues and youth empowerment.

Comedian, Miranda Hart, tweeted her support for the young person’s charity, Resurgo Trust, which improves the lives of disadvantaged young people. Vlogger, Tanya Burr, encouraged her followers to support Boundless Theatre, a charity working encouraging access to the arts. Whilst Arlene Phillips asked the public to support the charity, Candoco Dance Company; the group of disabled and non-disabled dancers which blew Strictly Come Dancing viewers away with their moving performance on Sunday evening.

The Big Give also roped in Channel 4 Newsreader, Jon Snow, and Irish rock band, Kodaline, to help promote the Christmas Challenge through providing the voice and music for its campaign video which has been shared widely on social media.

The Big Give is the brainchild of Sir Alec Reed, founder of the Reed recruitment business. To date, the Big Give has been responsible for raising £100m for good causes through their website.

Anyone wishing to have their donation doubled can do so by visiting before 4th December.
