More people searched for Facebook in the UK last week than for MySpace; more evidence that the social network is rapidly closing the gap on its rival, according to stats from Hitwise.

Though MySpace still has a 41% larger share of UK visits than Facebook, the search stats point to the growing popularity of Mark Zuckerberg’s site.

They show that the gap between Facebook’s UK visits and those of rivals Bebo and MySpace has been narrowing rapidly this year, from 265% in January to just 41% last week.

Recent stats from Nielsen//NetRatings also showed faster  visitor growth for Facebook, with MySpace’s UK visitors falling by 300,000 in May.
