It is unusual for the government to commission legal advice into the running of the Commons and raise questions about the supremacy of Parliament.
Chris Bryant, chairman of the Standards and Privileges Committee, questioned why the Cabinet Office commissioned legal advice from a senior QC on behalf of Mr Johnson, an individual.
Mr Bryant, a Labor MP, has withdrawn from his committee’s inquiry into whether Mr Johnson misled the Commons.
If Mr Johnson is found in contempt he could be suspended from Parliament – and even risk losing his MP seat in a by-election.
How Johnson could return
However, Mr Johnson is likely to run for the premiership again after winning the money, provided he escapes parliamentary censure on the party door, a close ally has claimed.
Lord Marland, a Tory peer who led Mr Johnson’s campaign for London mayor and is a longtime friend, said there was a “strong possibility” he was aiming for No 10 again.
He described the scenario in which he could return, which would not be great news for his successor.
