Even after 42 resignations today from govt what happens if Boris don't resign then Conservative party vl change the law of 1922 committee cause according to present law after he won vote of confidence recently there is no second vote of confidence in one year.
After that it will be difficult for Boris to survive Conservative party vote of confidence & he will go finally. Humiliated & defeated by his own party.
No MPs want to loose next election. Boris is a Liability.
