All Welsh Conservative MPs and at least one Welsh Labour MP are reported to be ready to abstain or vote against the government's gay marriage plans. The controversial proposals are due to be debated in the House of Commons later.
Conservative MPs have been given a free vote on the controversial proposals which allows them to vote according to their conscience. Some reports suggest that up to 180 could vote against the plans including some cabinet ministers.
By allowing a free vote, David Cameron avoids a damaging split but such a large number of internal opponents will still be seen as a blow to his leadership and efforts to modernise the party.
The most senior of the Welsh Conservative MPs likely to vote against the proposals is the Secretary of State for Wales, David Jones. When he spoke to ITV Cymru Wales yesterday he would only say that he would be 'voting as a constituency MP'
His deputy, Wales Office minister Stephen Crabb is said to be opposed. Simon Hart, who represents Carmarthen West and South Pembrokeshire, told me that he's sent a letter to all those he's written to saying he'll be voting against the plans. And Montgomeryshire MP Glyn Davies told me:
Cardiff North MP Jonathan Evans told the Western Mail that he also planned to vote against the proposals.
Liberal Democrat, Plaid Cymru and most Labour MPs are set to back the proposals. The only Welsh Labour MP thought to be likely to oppose them is the former Welsh Secretary Paul Murphy, who's one of a handful of Catholic MPs with objections and the reason why Labour leader Ed Miliband is offering a free vote to his party.
Another area of concern has been the position of the Church in Wales. The Government's legislation prevents single-sex marriages being carried out in Anglican churches but, unlike the Church of England, the Church in Wales is disestablished and was angry at not being consulted about the ban.
A compromise has now been reached which upholds the ban but gives the Church in Wales a means of easily overturning it in the future. A Church spokesperson issued this statement:
