By-elections when an MP leaves their party
Rejected
21 signatures
What the petition asks
When one or more MPs leave their party to form a new political group, this should trigger a by-election.
This will prevent MPs from representing the political interests of a party which differs from the manifesto they were elected under and ensures constituents are represented in the commons
