Ian Paisley Jr: 'MPs must unite to sustain the Union'

17 October 2012 Last updated at 14:21 BST

Ian Paisley Jr, the DUP MP for North Antrim, has urged Prime Minister David Cameron and his fellow members of the the House of Commons to "unite in a campaign to maintain, sustain and support the Union".

His comments at Prime Minister's Questions followed Monday's agreement between Westminster and Holyrood - which paved the way for a Scottish independence referendum in 2014.

In response Mr Cameron said he hoped that "politicians of all parties will agree to share platforms together" in the campaign to keep the UK united.
