Watch furious scenes as Chorley MP Sir Lindsay Hoyle throws out two Scottish MPs from the House of Commons during Boris Johnson's PMQs

Alba Party pair Kenny MacAskill (East Lothian) and Neale Hanvey (Kirkcaldy and Cowdenbeath) were ordered to leave the chamber by Speaker Sir Lindsay Hoyle in furious scenes at the start of the session.

Mr MacAskill could be heard trying to raise a point of order and appeared to say “we need a referendum”, before he was drowned out by other MPs.

He then refused to sit down and continued to speak, prompting Sir Lindsay to act.

The Speaker said: “I will not tolerate such behaviour. If you want to go out, go out now.

“If you stand again, I will order you out. Make your mind up.”

Mr MacAskill rose to his feet again before Mr Hanvey also stood up and started speaking, but he could not be heard over the heckling from Tory MPs.

Sir Lindsay then named the pair, meaning they are suspended from the House.

He said: “Neale Hanvey, I’m now naming you and Kenny MacAskill to leave this chamber. Serjeant, deal with them.

“Out now, Serjeant-at-arms escort them out.”
