Anyone else by now would have shown some form and resigned.
Resign and lose all the cash and perks that come with being an MP?
Career MP's never resign unless they are pushed and have no other option.
More than likely things just get hushed up and covered up as in the Todd Barkley incident.
In the meantime we get to watch blatantly deceptive politicians wriggle and squirm as they try to reassure us they are honest all the while doing all that they can to ensure their wages and perks continue to be paid.
