The Tory peer sparked confusion when he gave an over-the-top apology for not being on time to answer questions from the dispatch box, missing a question from Labour’s Baroness of Burtersett.

“I have always believed we should rise to the highest possible standards of courtesy and respect in responding on behalf the government to the legitimate questions of the legislature,” he said.

“I am thoroughly ashamed of not being in my place and therefore I shall be offering my resignation to the prime minister with immediate effect.”

As Bates turned and walked out of the chamber, peers yelled “NO!”

After he left, Labour Baroness Smith insisted Bates had no reason to resign for the “minor discourtesy” and all that was needed was an apology.
