David Cameron has spent nearly a year attempting to convince Conservative MPs the law needs to be changed to allow same-sex couples to marry in England and Wales.
But one person he has yet to convince is his own mother.
Speaking to The Telegraph, Mary Cameron was asked why her son was pressing ahead with legislation when it was supposedly ‘alienating’ Conservative supporters.
‘I know, but David just won’t be told,' she said.
While it may give many hope the British Prime Minister supports same-sex marriage even at Sunday lunch, Mother Cameron said she did not support marriage equality.
The 78-year-old, whose father was Sir William Mount, 2nd Baronet, is a retired Justice of the Peace.
Her comments come as the Marriage (Same-Sex Couples) Bill is officially published today (25 January).
The second reading will come on 5 February, and then the bill will have to pass through committee and report stages in the House of Commons, as well as a third reading.
It will then have to go through a similar process in the House of Lords before it becomes law.
