An MP who donated £14,000 to Comic Relief after promising to pay £1 per retweet says she hopes her act will encourage more wealthy people to give more to good causes.

Slough MP Fiona MacTaggart posted the message at 20:25 GMT and gave people a retweet deadline of 21:00.

The Labour MP thanked the 14,268 retweeters for "being so generous for me" and posted that she had "no regrets" despite being "Twitter naive".
