Gordon Brown: Time to stop pitting Britishness against Scottishness

A "muscular unionism" approach by Boris Johnson is making Britishness compete with Scottishness, former Labour prime minister Gordon Brown has warned.

He said there was a stand off between Westminster and Holyrood and a four-nations forum was needed.

Mr Brown is urging the prime minister to co-operate on the big issues and provide better explanations on the benefits of the United Kingdom.
