There is a "growing gap" between David Cameron and the Conservative Party, according to one of the party's MPs.
Brian Binley MP said Mr Cameron was made leader because "we thought he was a winner" but had now "done a few things that the party in the country overall didn't want him to do".
Mr Binley called for an investigation into whether a close ally of the Prime Minister had dismissed grassroots activists as "mad, swivel-eyed loons", but his request was rejected by the party's board.
While welcoming Mr Cameron's conciliatory email to party members, Mr Binley told BBC Radio 4's Today programme: "He may believe in them but we are talking about the gap between himself and the party."
"I think it is a growing gap," he said, but added: "I think it can be put right and I think David Cameron is listening as proved by the fact that actions are now being taken."
David Cameron sent an email to members of his Conservative Party urging unity.
The Tory grandee Lord Howe has accused the Prime Minister of 'losing control' of his party as divisions over Europe come to the fore.
The Conservative Party has moved to head off a row with grassroots activists after a Tory ally reportedly described them as "loons".
