Controversial US "pick-up artist" Julien Blanc has been barred from entering the UK by the Home Office.

The self-styled "dating guru" holds seminars claiming to teach men how to attract women but his methods have been widely criticised as sexually abusive.

A petition to deny him a visa attracted more than 150,000 signatures ahead of his UK tour, due to start in February.

Mr Blanc has apologised, saying his intention was "a horrible attempt at humour" taken out of context.
