Mark Menzies MP has lost the Conservative Party whip after allegedly misusing party funds.
Mr Menzies denied claims in The Times newspaper that he asked party members for money and then repaid them using campaign funds.
Defence Secretary Grant Shapps refused to comment on the allegations when questioned by Kay Burley.
Last week, William Wragg also gave up the whip after he admitted to The Times that he had given his colleagues' phone numbers to someone he met on a dating app.
Scotland Yard said it is investigating reports of a so-called "honeytrap" scam after politicians and journalists received unsolicited messages from people attempting to engage them in conversation.
