[quote=@KnightShade]Write to them anyway. You may not have voted for them but they still have to represent their constituents, they're supposed to at least listen to your views even if they disagree.[/quote]

Neither my local MP nor her strongest competitor (whom I voted for) have any power at all, because neither of them are members of the party that currently has a majority in the House of Commons. Even if I influenced my MP somehow by writing them, they wouldn't be able to do anything on my behalf.
