Chris Ames, deputy editor of Transport Network website and Highways magazine, accused Dan of “Labour bashing” on BBC breakfast. He said: “Classic Labour bashing dragging a non issue about Scotland into an interview about education. “The contradiction you based your repeated questions on is a figment of your own intellectual inadequacy.” Dan was uncharacteristically befuddled in his reply.
He said: “Struggling to understand this tweet. The words you’re using are too long and are confusing my simple brain.”
Mr Ames then gave Dan a lesson in Scottish politics.
He explained that: “Labour set up the Scottish Parliament to give Scotland a degree of control over its affairs.
“It follows that Westminster doesn’t overrule Holyrood every time it disagrees with it, it’s really not difficult.”

Dan soon dropped his disingenuous tone and let rip at Mr Ames.
His reply read: “Chris. I really don’t mind you disagreeing with me or even thinking I’m rubbish at my job. I don’t get the insults. You’re a journalist. You’re better than that.”
The presenter is no stranger to Twitter debates.
