Andy Burnham was today accused of 'running scared' after Labour moved to ensure the incoming prime minister won't face the House of Commons for at least six weeks.The Government took 'unprecedented' action on Tuesday to derail Tory plans to force a Commons vote on whether to push back MPs' long summer break.The Conservatives want the Commons' six week recess to be delayed by one sitting day so that Mr Burnham can face questions from MPs on his policies.As it stands, Mr Burnham is set to replace Keir Starmer as PM on Monday next week - after MPs have already headed away from Westminster this Thursday.MPs are not due to return to Parliament until 1 September, meaning Mr Burnham won't have to face the Commons for at least the first 43 days of his premiership. It has added to growing concerns about the former Greater Manchester mayor's mandate to lead the country and his dodging of scrutiny over his plans.The Tories wanted to use tomorrow's planned Opposition Day in the Commons to debate delaying the summer recess until next Monday.But Labour's Alan Campbell, the Leader of the House of Commons, announced a change so MPs will instead debate the conflict in Iran and a statutory instrument related to national security. Andy Burnham has been accused of 'running scared' after Labour moved to ensure the incoming prime minister won't face the House of Commons for at least six weeks Labour's Alan Campbell, the Leader of the House of Commons, announced the Government has cancelled Wednesday's planned Opposition Day debateAn Opposition Day is one of several days during the parliamentary session when the Conservatives are guaranteed a debate on a motion of their choice.Tory leader Kemi Badenoch fumed at Labour's decision to cancel Wednesday's planned Opposition Day debate.'In an unprecedented move, Labour have scrapped the Conservative vote to force Andy Burnham to come to Parliament to answer questions when he becomes PM on Monday,' she said.'Labour are running scared because they know the honeymoon will be over the minute he has to tell us his plans.'Jesse Norman, the Tory shadow leader of the Commons, said the decision not to debate delaying summer recess was 'a total humiliation and embarrassment for the Government'.Mr Norman said the Conservatives want to push back MPs' summer break until Monday 'to enable the new PM to make a statement about his plans for Government'.'The Government has a majority of more than 150 and it could not trust its MPs to vote the right way on that motion,' he added.'And it could not bear the idea of a new PM facing any scrutiny before September.'A PM, let me remind us all, who has been chosen by a coronation not a contest, with no known platform, almost no known policies and no idea of his priorities or indeed his Cabinet team.'Mr Norman continued: 'It is the worst possible start for a new PM.'People across this country will see what has happened and they will conclude that this is a man who is frit, running scared of public scrutiny before he can even take office.'Sir Alan defended his decision to change Wednesday's agenda, claiming he had not seen the Conservatives' draft Opposition Day motion.'It was not tabled for tomorrow, we did not see the words of the motion,' he added. 'A decision was made on whether or not the House should debate an unfolding international crisis or not.'Referring to the general debate on Iran, which will now replace the Opposition Day debate, Sir Alan told the Commons: 'I do, first of all, appreciate the frustration of members when business is changed at short notice and debates are postponed.'But members will appreciate the importance of the House being able to discuss the escalating and fast-moving situation in the Middle East before the recess.'In a point of order, Tory whip Paul Holmes said the Government had been made aware of the subject of tomorrow's planned Opposition Day debate through 'the usual channels'.Sir Alan replied: 'When we made this decision, that was not clear. We did not know that. No we didn't.'The decision therefore was taken to go with the situation in Iran, rather than hang around and wait for what the Opposition might come up with.'Mr Burnham exited a major speech at the end of last month without taking questions from the media.He has also ruled out calling a snap general election when he enters Downing Street, despite having previously demanded the Tories go to the polls when they switched leaders while in office.Mr Burnham has the backing of at least 349 Labour MPs to become their party leader.It is now mathematically impossible for another Labour candidate to secure the 81 supporters necessary to launch a late bid for the keys to No10.A spokeswoman for Mr Burnham did not comment when asked if he had held any conversations with the Government about axing tomorrow's Opposition Day debate.
