LONDON - British Prime Minister Gordan Brown's wife, Sarah, has apparently become one of the country's most popular Twitter users.

Over 776,000 people are said to follow her updates, exceeding the avid fanbase of one of the nation's foremost wits, Stephen Fry.

Since she signed up to the micro-blogging site in March, her regular comments at "SarahBrown10″ have fast become a favourite among people.

Even popular television presenters like Jonathan Ross and Russell Brand are unable to compete with her Sarah's following.

Whether Sarah would ever become so popular on the social networking site would have been unthinkable only two years ago, for she was almost silent figure then and often the subject of cruel jibes over her image.

Now that her public persona has changed, some aides in Downing Street call consider Sarah to be a "real asset" for the Labour Party.

Some even believe that the party may benefit from Sarah's rising profile.

"In political terms, Sarah Brown's rise on Twitter could be significant. Although the content is deliberately not party political, she is effectively pressing voter flesh online, as she did in person at the Glenrothes by-election to great effect," the Scotsman quoted Ross Furlong, an online public relations expert, as saying.

Sarah has recently tweeted about attending the G20 dinner in Pittsburgh in the "lovely environment" of an organic farm, besides urging followers to sign up to the "Million Mums" campaign against mortality in childbirth.

She has also revealed that she was introduced to Twitter by a friend after expressing a wish to "open up the details of what I do without wanting to sign up to a big commitment like writing a regular blog."

"Twitter works for me as a great way of sharing details of campaigns I am working on and providing better transparency about how I spend my days," she said.

Furlong added: "It's a way of going around the constituency and shaking people's hands, but in front of a huge audience."

Not all of Sarah's tweets are directly linked to good causes, for she has also written about cinema trips, home baking, baby strawberries, and even ironing. (ANI)
