Speaker Lindsay Hoyle is set to meet with the Mail on Sunday's editor to discuss an article which claimed Angela Rayner tries to district Boris Johnson in the Commons by crossing and uncrossing her legs.
Sir Lindsay said the claims were “misogynistic and offensive” and could well deter women from standing for election.
The Mail on Sunday's piece included a quote from one anonymous Tory MP who said that Ms Rayner “knows she can’t compete with Boris’ Oxford Union debating training, but she has other skills which he lacks”.
