The X-Men star Hugh Jackman has asked fans on social networking website Twitter. com to tell him about their favourite charities - so he can donate $100,000 (£67,000) to the most worthwhile organisation.

Jackman writes on his official Twitter page: "I will donate 100K to one individual's favourite non profit organisation. Of course, you must convince me why by using 140 characters or less.

"The more passion shown for your charity the better! Get the support of your friends and teach them the importance of giving." - Sampurn Media
