A chapel located beneath the Palace of Westminster is being considered as a venue for gay weddings.

A bill which seeks to make England the twelfth nation to legalize gay marriage received an initial nod from the House of Commons in February.

Under the proposed marriage reform, churches will be allowed to marry gay and lesbian couples. However, the Church of England is to be exempt from the new law.

Under a plan being considered by ministers, the Anglican chapel of St. Mary Undercroft, a popular marriage venue for members of parliament, would be changed to a multi-faith prayer room.

Converting the chapel to a multi-faith area would allow gay couples to be wed by ministers from other faiths which wish to do so. Such denominations include Quakers and Liberal Jews.

According to the UK's The Telegraph, the proposal is being championed by MP Chris Bryant, a vocal supporter of marriage equality.

Noting that the chapel is already being used to hold Catholic masses, Bryant called it “odd” that other faiths were left out.

“St. Mary Undercroft has been many things in its time,” Bryant told the paper. “It was the Speaker's dining room and before that Cromwell used it to stable his horses.”

“It is a bit odd that we have no place for people of other faiths to worship. If we have got over this hurdle with Catholic masses being celebrated there, it seems odd not to allow services of other denominations to be held there.”

The chapel was completed under King Edward I in 1297 and survived a massive fire in 1834 that destroyed the Houses of Parliament, which are located above it.
