Boris Johnson has been accused by Sir Keir Starmer of “not lifting a finger” on rail strikes as PMQs got under way on Wednesday. The Commons showdown is the first since the publication of the controversial Northern Ireland Protocol Bill as the UK faces renewed legal action from Brussels. The Prime Minister has downplayed changes in the bill, which has been criticised for seeking to unilaterally tear up parts of the Brexit agreement, as “not a big deal”.
