ALMOST £7 million has been raised in Britain through the Ice Bucket charity challenge.

The Motor Neurone Disease Association (MNDA) said they were grateful for all the money raised.

Brian Dickie, the charity's Director of Research, who did the challenge three times, told Good Morning Britain the organisation wanted to say "a big thank you " to everyone who had taken part.

The charitable act, which involves people upending buckets of ice cold water over themselves, became an online craze earlier this year, spreading to the UK from America where proceeds went to ALS, a type of Motor Neurone Disease.

Since then participants have donated to various charities, but MNDA said they had gained £6.8 million after a "phenomenal" and "unprecedented" response.

Celebrities including Benedict Cumberbatch and Jennifer Aniston, as well as former US president George Bush and even Vogue editor Anna Wintour are among those seen to be drenched in cold water in online footage.

Many have posted their videos on Facebook and Twitter and nominated others to follow in their footsteps by taking the challenge and donating money to their chosen charity.

Earlier this month police in Sussex warned people to be careful after a cyclist was injured when a friend threw a bucket of icy water over him as he rode his bike.
