I strongly disagree.
If a candidate did not want to be associated with a political party, stand on a party manifesto, campaign on party lines they should stand as an Independent, which obviously some do.
MP's who have been content to be associated with, fought for a political party, campaigned for a political party , stood on a party manifesto and quit should in principle be second to the electorate who should take precident over the MP and the constituency should have the right to make their choice if they want that MP to still represent the constituency or not.
Each to his her own opinion I guess.
This is not a bias political issue and I think the high volume of MP's who are now sitting as Independents will eventually force Parliament to revisit the reasons for calling a bi-election.
