AFP: Britain will announce plans next week to allow gay marriages in churches and other religious buildings, officials said today, although Prime Minister David Cameron insisted no faith group would be forced to hold them.        

Culture Secretary Maria Miller will unveil ministers' responses to a consultation earlier this year, which will propose that religious organisations should be able to 'opt-in' to hold same-sex weddings, according to a government source.        

Amid strong opposition from the Church of England and Roman Catholics, however, as well as many members of Cameron's Conservative party, Miller will stress that no religious groups will be forced to conduct gay weddings.         Speaking to reporters on a visit to a car factory, Cameron said: "I'm a massive supporter of marriage and I don't want gay people to be excluded from a great institution.'
