Every Member of Parliament has a fiduciary duty to the whole electorate. This fiduciary duty is that of loyalty to the trust given by the electorate. This duty has to be fulfilled at all times.

This is what Edmund Burke had to say on the duties of Members of Parliament: "It is the member's duty to sacrifice his repose, his pleasures and satisfactions to those of his constituents - and above all always to prefer their interest to his own".
