Hi
Whilst not wanting to comment on individual cases, I think we must bear in mind we are a, “representative democracy” and as such we vote for a person NOT a party. Prior to the mid sixties party affiliation was not put on the ballot paper.
In the last Westminster parliament there were the “defection” of Emma Nicholson from the Conservative benches to Liberal also Shaun Woodwood Conaservative to Labour.
Reg Prentice in an earlier parliament was a high profile “defection” from Labour to Conservative.
In many cases, they claim that their party has moved from its original position and they more represent their electorates wishes by their move.
I think,we must look at the length of time since they were elected, if it is measured in weeks rather than years then their reason are suspect.
