The most powerful gay man in Britain is recovering well after an operation on his prostate.

Lord Mandelson, First Secretary of State and Secretary of State for Business, underwent surgery at St Mary’s Hospital in London on Friday.

He was released on Saturday and said the operation on his enlarged prostate was a success.

“I have been treated really well,” he told reporters.

“Everything is now flowing extremely well.

“Actually I have had a jolly time.”

Lord Mandelson, 55, added that he is “very proud” to be an NHS patient.

According to the BBC, benign growth of the prostate is common and around one in three men over the age of 50 suffer symptoms due to an enlarged prostate.

Just days after he returned to the government in October 2008, after more than seven years away from frontline British politics, Lord Mandelson underwent surgery at St Mary’s to remove a kidney stone.
