UK mps defections is a democracy fraud and it should be outlaw as soon as possible by the government. Mp like Sam gyimah should not be allow to use his conservative vote to join the liberal democrats or any other parties because the constituency that elected him didn't vote for liberal Democrats. Mps shouldn't be allowed to join other parties without a by-election. Mps like sam, Dominic will loose any by-election. This is another way of saying to their constituency that they are stupid.Voters or constituency should be allowed to withdraw their vote if the mp decided to join another party. Is insane to carried conservative party vote to liberal Democrats or any other parties.
