Ian Blackford has called for the Scottish National Party to be included in ITV's general election debate on Tuesday. The SNP's Wesminster leader raised concerns that many people make their mind up on who they will vote for on the basis of the televised debates. He added that the SNP, who are the third largest party in Wesminster, have brought a case against ITV at the High Court for the sake of their party and on behalf of other parties as well.
