The chairman of the Brexit select committee will be a Labour MP and so far Hilary Benn is the only candidate. There are no challengers – yesterday Margaret Hodge told colleagues to let Benn take the job. There is however growing opposition from Labour Leavers. John Mann tells Guido: “It should be a Brexiteer”. Would he consider running? “We will all have to consider it,” Mann says of himself and fellow Labour Leavers. Remember, the Brexit committee chairman will be decided by a vote of all MPs. John Mann or Gisela Stuart would be a popular choice with Tory MPs who want to make sure the government delivers. Benn is an arch-Remainer, he believes we should stay in the single market and says immigration numbers will not come down. Select committees are supposed to hold ministers to account, not obstruct them. Benn is far from the best person to make sure Brexit means Brexit. Surely MPs should choose a Leaver if they want to hold May’s feet to the fire…
