Hedge fund manager Crispin Odey has denied indecently assaulting a woman more than 20 years ago.
The Tory donor, 61, was charged on 14 May this year over an alleged incident at an address in Chelsea, west London, in 1998.
Prosecutors said he is due to appear at Westminster magistrates court on 28 September following a complaint by a woman.
The Metropolitan police said Odey is alleged to have indecently assaulted “a woman over 16 years of age” on or around 13 July 1998 at an address in Swan Walk, Chelsea.
Odey, of Swan Walk, said in a statement on Friday: “The allegation is denied and I will strongly contest this matter.”
The influential financier and founder of Odey Asset Management was a high-profile backer of the Brexit campaign, who donated more than £870,000 to pro-leave groups.
