To create a new law a member of parliament will initially put forward a green paper. This paper is one which gathers evidence and opinions on a given subject whether that be a public opinion or one of other MPs. Following this collection of information the member of parliament or a body of MPs, shall submit a white paper. This white paper outlines proposals for a new bill and again gathers opinions on what different people think of the proposed bill. If the opinions are in agreement with the proposal, a bill is drafted and the first reading begins. In the first reading, the bill is merely announced to parliament that a new bill is in circulation, on the second reading the proposed terms are read and MPs vote on any amendments they would wish to make. The next stage is the committee stage. MPs consult various professional bodies regarding the effects of the new bill and gain professional opinions on the terms. The third reading then takes place again allowing for any amendments and the bill then is sent over to the opposite house, if the bill started in the commons it is sent to the lords. The same process occurs in the Lords however when a term is found that the Lords do not agree with, the Bill is sent back to the commons, this is the ping pong effect. After all the terms are agreed by both houses, the reigning monarch gives her obligatory royal assent and the bill is an act of parliament.
