Civil unions are possible since 2005 and give the same rights as the marriage but until now, it was laic.
The Minister for Equalities, Lynne Featherstone, announced that the "government will stop this ban and civil unions could be held in churches" starting from December 5th. She however specified that each church would decide to celebrate or not the unions.
Catholic Church and Church of England already said that they won't "authorize the civil unions to be held in their Churches".
Edward Leigh, conservative member of Parliament, thinks that "all the interest to ban churches to held the ceremonies of civil unions is to show very clearly that civil unions are not marriages."
Useless because Prime Minister David Cameron decided to open the marriage to gay and lesbian couples during his mandate.
