British PM David Cameron apologises for 'Queen purred with joy at Scottish vote' remark

David Cameron has contacted Buckingham Palace to offer his apologies after he made a blunder by saying that the Queen "purred" with joy at the Scottish independence referendum results.

The British prime minister, 47, said that he regretted the comment he made while talking to media tycoon Michael Bloomberg at a trade fair, was very "embarrassed," and would apologize to her highness, Queen Elizabeth II, in person too when they meet next, the Mirror reported.

His remarks were condemned by Labour's shadow Defence minister Kevan Jones and Scotland's First Minister Alex Salmond.

Cameron said that though it was a private conversation, he shouldn't have said what he said and won't make the mistake again.

Cameron is currently in New York to attend the United Nations General Assembly, and was speaking to Michael Bloomberg, the former mayor of the city, when TV crews accidentally picked up his remarks. 

"She purred down the line. I've never heard someone so happy," Cameron, whose Conservative Party campaigned for Scotland to stay in the United Kingdom, said of the Queen, according to BBC TV and Sky News.

However, as the prime minister is forbidden from speaking about his conversations with the monarch, Cameron has breached the convention, which also exposes the Queen, who has so far maintained her traditional neutrality over the issue.
