Roberts: Tories should be careful what they wish for

English historian Andrew Roberts and Scottish comedian Hardeep Singh Kohli discuss the subject of nationalism, which is playing a key part in the general election campaign.

The Conservative historian reckoned Conservatives "should be careful what they wish for", with his fear that 5 million Scots would hold ten times as many English people to ransom.

But the SNP-supporting comedian said Scottish nationalism was like "no other movement we have witnessed in Western Europe" since World War ll. And he predicted: “The Scots are coming in numbers”.
