Sir Bill Cash has expressed his confusion at three Conservative MPs leaving the party over their Brexit concerns.
Anna Soubry, Heidi Allen and Sarah Wollaston have now joined the Independent Group, and cited a "disastrous handling of Brexit" as their reason for leaving the Conservatives.

Speaking to talkRADIO's Daisy McAndrew, Sir Bill said: "There is a complete mismatch between the reality of a democratic decision making process, and the fact that people who don't like it simply say we don't like it, so we're going to stomp off in another direction."
He added: "I have been known as a rebel over the years, and I voted in accordance with what I believed to be right, but I didn't vote against a decision taken by the British people in a referendum."
'Been through bigger crises'

The move by the three Conservative defectors has led to speculation that the party could be in trouble, but European Scrutiny Committee chair Sir Bill insisted the party had survived "bigger crises".
"The Conservative Party has been going for an extremely long time and it has been through bigger crises than this by a very long way," he said.
"This is being driven by democratic process, and some people just didn't like the idea of it."
