David Cameron: Trump's Muslim ban "divisive, stupid, wrong"

The British reaction to Donald Trump continued to worsen Wednesday, with Prime Minister David Cameron joining in with his own criticisms of the GOP front-runner for his recent call to ban Muslims.

"I think his remarks are divisive, stupid and wrong," Cameron said Wednesday.

He was responding to a proposal from a British lawmaker to prohibit Donald Trump from entering the U.K., an idea that started with a popular petition that gained steam over the last week.

Since Trump's suggestion for a "total and complete shutdown" of Muslims entering the U.S., the online petition to bar the billionaire has gathered over half a million signatures to date -- more than five times the number necessary for Parliament to consider it for debate.

The prime minister added that, while he was "proud" of leading a nation that is "one of the most successful multi-racial, multi-ethnic, multi-faith countries in the world," he disagreed with recent calls to ban Trump from the country.

"I think if he came to visit our country he'd unite us all against him," Cameron said.

The idea of a ban on Muslims is just as unpopular in the U.S., with a majority of the public opposing the proposal, according to a recent CBS News survey. Fifty-eight percent of people polled disagreed with the Trump proposal to temporarily ban Muslims from other countries from entering the U.S., while 36 percent said they supported the ban.

Trump is also losing legally on British soil. On Wednesday, Britain's Supreme Court ruled against the presidential contender in his battle to stop a wind farm from being built next to his golf resort in Aberdeen, Scotland.

The Trump Organization called the verdict "extremely unfortunate" and said the wind farm would "completely destroy the bucolic Aberdeen Bay and cast a terrible shadow upon the future of tourism for the area."

The court loss prompted Alex Salmond, a British lawmaker and a former First Minister of Scotland, to call Trump, in an interview with CNN, "once, twice, three times a loser."
