Zack Polanski, the deputy leader of the Green Party, has admitted to performing hypnotherapy to 'enlarge' women's breasts in the past.
LBC's Tom Swarbrick asked Mr Polanski about the practice after an article by The Sun from 2013 resurfaced about him performing the practice at a hypnotherapy clinic on Harley Street.
In the 90-minute sessions allegedly costing £222, women were told to visualise themselves with bigger breasts.
On Wednesday, Mr Polanski apologised for his past actions and said he never believed them.
"It does not represent my work, it does not represent me."
Mr Polanski added he never charged for the service.
