A self-described pick-up artist who promotes manipulating women into having sex has been forced to leave Australia after the federal government cancelled his visa.

Julien Blanc, of the United States group Real Social Dynamics, was in Australia to share his controversial dating tactics at a series of seminars.

His methods, which include emotional manipulation, choking and pulling women into his groin, have caused widespread outrage.

The Melbourne hotel which was planning to host his talk on Wednesday cancelled amid an outcry on social media and an online petition which attracted thousands of signatures.
