The Scottish parliament could provoke a constitutional crisis over Brexit, says former first minister Alex Salmond.

Scottish Conservative chief whip John Lamont said: "The SNP is quite happy with constitutional upheaval so long as it forwards its separation goals."

Scottish Labour leader Kezia Dugdale said Mr Salmond's comments prove the SNP "thrives" on constitutional crisis.

Mr Salmond's comments were made in the Sunday Politics Scotland programme on BBC One.
