Let's be quite clear...

...an MP is elected to represent their constituents, and to act in their best interests. When performing in their official capacity therefore, an MP's personal views and beliefs are irrelevant, except in so far as they may represent the views and beliefs of their constituents. The current situation concerning the proposed embryo research legislation, where some MPs have indicated their intention to vote against the Bill purely on religious or moral grounds is totally unacceptable. An MP who says "I personally do not agree with this, therefore I will not vote for it" is simply not doing his or her job properly.
