Supporters said to fear that 30-day Commons ban for Covid breach would set a precedent if Johnson faces similar vote
Allies of Boris Johnson have been accused of preparing to block a motion to suspend the disgraced Scottish MP Margaret Ferrier, leading the government to postpone the vote in parliament.
It is believed that supporters of the former prime minister feared that a vote to suspend Ferrier for 30 days over a breach of Covid-19 rules could set a precedent if Johnson faced a similar vote.
