Britain's Home Secretary Theresa May is allegedly going to block Julien Blanc from entering the UK after the techniques used by controversial 'pick up artist' (PUA) were deemed "racist and sexist".

US citizen Blanc, whose 'pick-up artist' techniques includes grabbing women's heads and pushing them towards his crotch, has already had to end his Australian leg of his tour after the country withdrew his visa.

Sky sources say that May will not let him enter the UK.

The Home Office told IBTimes UK:

"The Home Secretary has the power to exclude an individual if she considers that his or her presence in the UK is not conducive to the public good or if their exclusion is justified on public policy grounds.

"It is longstanding practice that we do not comment on individual exclusion cases unless they are made public by the excluded individual.

"This Home Secretary has excluded more foreign nationals on the grounds of unacceptable behaviour than any before her."
