Ban sitting MPs from changing party.

Background

Ban sitting MPs from changing party, and instead require them to stand down so that they can compete for their new chosen party in a bi-election.

Additional details

Despite MPs being representatives of their constituents, most people vote for a Party rather than for an individual to represent them. As such it is completely unreasonable for an MP elected for one party to subsequently switch to another without going back for the support of their constituents.
