MPs have voted to get the Commons privileges committee to investigate the SNP MP John Nicolson over a complaint that he broke Commons rules by revealing the contents of a letter he received from the speaker, Sir Lindsay Hoyle. (See 3.37pm.) Nicolson wanted people to know why Nadine Dorries, the former culture secretary, was not going to face any penalty after a report concluded she had misled the culture secretary. Correspondence from the speaker is meant to be treated as confidential. The Tory MP David Davis tabled the motion saying Nicolson should be investigated and he told MPs that Nicolson broke the rules when he discussed, in a video he posted on Twitter, what Hoyle said. Davis said: Nowhere in his filmed statement did he tell his followers that Mr Speaker was following normal precedent or normal procedure by accepting the will of the [culture] committee. All of us in this house have a duty to uphold its rules and institutions, but by knowingly breaching the confidentiality of the speaker’s correspondence he has done the opposite of that. This is a clear breach of our rules. Nicolson said people would find it “curious” that Dorries was not being punished for misleading a committee, but that he was being penalised for letting people know about this. Michelle Donelan, the culture secretary, has defended removing a provision in the online safety bill to regulate “legal but harmful” online material, after the father of teenager Molly Russell said it was a “watering down” of the bill. Neil Basu, the outgoing assistant commissioner of the Metropolitan police, has described Suella Braverman’s language about immigration as “horrific”. (See 5.04pm.)
