The polyp removed from Joe Biden’s colon last week was a benign, slow-growing but potentially pre-cancerous lesion that required no further action, his doctor has said.

The specimen, a tubular adenoma, was similar to one the US president had removed in 2008, Dr Kevin C O’Connor, physician to the president, wrote in a memo released by the White House.
