The Scottish Secretary David Mundell has called on the Democratic Unionist Party to "change its position" on LGBTI issues.

Theresa May is due to meet the DUP leader Arlene Foster on Tuesday to finalise a deal on propping up her minority government.

Mr Mundell, the Conservative MP for Dumfriesshire, Clydesdale and Tweeddale who has been reappointed Scottish Secretary, became the first openly-gay Conservative Cabinet secretary when he came out in January 2015.

Questioned on the DUP's stance on gay rights, he said he does "not subscribe" to the Northern Irish party's position.

Northern Ireland is the only part of the British Isles where same-sex marriage remains outlawed.

The DUP has repeatedly used a controversial Stormont voting mechanism - the petition of concern - to prevent legalisation despite a majority of MLAs supporting the move at the last vote.
