The Parliamentary Law of the United Kingdom contains detailed rules about the privileges and the interests of the Members of Parliament. Since 1975, the MPs are obliged to give a statement about their financial interest in affairs that are subject of discussion in Parliament or in the parliamentary committees. If a concrete financial interest of the MP is identified, that MP will be excluded from voting. However, nowadays, this rule is very rarely applied and the MPs are exempted from voting only when it is a matter of so-called private bills, i.e. this rule is not applied to the public, i.e. government's draft laws.
