Do the MPs loyal to their party in the UK

In this course work we were given the theme about how MPs are devoted to their party. The plan that I am going to follow is about representation and the main role of the whips, in what do they focus on. In addition, I will provide examples when MPs voted against their party such as the situation in Iraq.
One of the most important roles of an MP is representing and supporting his or her party, its ideology, policies and views on how to govern the country. They are expected to act in the interests of their party, and in most case this means that they should vote in the House of Commons for the bills that are introduced by their parties.
