Which for me highlights a major failing of our political/electoral system.
Most of the country never gets any say/vote as to who is PM. Massively powerful position and vast majority have no vote.
Some say our vote for our constituency representative is often treated as a vote for a party rather than an individual representative, then when an MP changes Party and thus is their vote becomes determined by a different leader/whips then there should be an obligatory bye election.
Politicians treat our votes a delegating which it absolutely is not.
