Disgraced Braintree MP Brooks Newmark, who sent sexually explicit texts to an undercover reporter posing as a "Tory PR girl", asked for "a naked full body shot", it has emerged.
Mr Newmark resigned as minister for civil society this weekend after a Sunday newspaper informed Downing Street it would be publishing the story, and more information has since been released detailing the MPs involvement with "Sophie Wittams", a character created by the undercover reporter.
The Twitter account for "Sophie" featured a picture of a Swedish model and updates about "fitty" politicians. The account followed Mr Newmark as well as several other Conservative MPs.
The married father of five was sent a naked picture by "Sophie", to which he replied: "...resend without your hand in the way and legs parted and I will send something in return. That way we both have a secret".
"Assuming it meets my request and I reciprocate you MUST swear on a stack of Bibles you won't show pics as I promise not to show pics of you? OK?"
Mr Newmark did indeed respond with his own picture, exposing himself while wearing a pair of paisley pajamas.
He later added: "I want a standing full body shot but you can cover up any modest bits you wish".
The MP has since apologised for the scandal, telling the BBC: "'I have no-one to blame but myself. I have hurt those I care about most.
'I am so, so sorry. But I just need time with my family."
His resignation came a day ahead of the Conservative Party's last conference before the next general election, amid news that another MP,Mark Reckless, had defected to Ukip.
