It should also be remembered that being the Leader of Her Majesty’s Most Loyal Opposition is not the same job as being First Lord of the Treasury, Minister for the Civil Service and Prime Minister, and success in the former is no guarantee of success in the latter - Johnson being the obvious, perfect example.
