Jewish Conservative MP Brooks Newmark has resigned from the government over allegations published in a Sunday newspaper.
Mr Newmark, MP for Braintree, left his post as minister for civil society saying he remained “a loyal supporter of this government”.
A spokesman for the Prime Minister said David Cameron had accepted Mr Newmark's resignation.
The Sunday Mirror reported that Mr Newmark sent explicit images of himself to an undercover reporter posing as a female Tory activist.
