Peter Weir, of the DUP says his party will be opposing the motion, which he says is "an attempt at an electoral stunt".

He says the motion is attempting to re-define marriage which risks "losing the essence of marriage".

Mr Weir speaks about the impact of changing the definition of marriage on churches and religious institutions.

"If we see a situation in which the definition of marriage is redefined in this nature and various churches resist that, as they would, how long before pressure comes on them? How long before there is some level of court challenge or indeed pressure is put on them in terms of funding that goes to those churches".
