Baroness Sayeeda Warsi has claimed the Conservative Party has an "institutional issue" with Muslims and Islam.
Speaking to talkRADIO's Julia Hartley-Brewer, the former Conservative chairwoman responded to reports that 25 party members have been suspended over comments the party considered to be inapropriate.
One party member is said to have posted the following comment on Facebook: "I was going through a few magazines the other day down the local mosque. I was really enjoying myself. Then the rifle jammed."

"I really wish it was just a few bad apples," Ms Warsi told talkRADIO's Julia. "I have now been raising this matter since the end of 2015."
She said she had handed over "too many complaints" during her time in the party, and called for an "independent inquiry" to "clear the decks of this rot".
"I raised it with two successive chairman, I wrote a letter to the Prime Minister and absolutely nothing was done," she added.
"When a big fuss is made, when we're shamed into acting, we do something about it. This is absolutely an institutional issue. I have personally handed over too many complaints and seen too many complaints not dealt with."
