Safe seats will be reduced.  All political parties have seats that they consider safe and unlikely to lose. If a person in an inner city constituency that has a strong Labour history, wishes to vote for someone other than Labour, then their vote is effectively null and void. Labour will win a majority however they vote. The fact that the seat is so safe means that there is effectively very little effect people can have, resulting in thousands of people's vote being wasted and having no effect when it comes to forming a government. In the 2010 UK general election the result was decided by less than 460,000 voters in only 111 constituencies. This gives an unfair amount of political influence to a tiny minority of the electorate while making the majority’s votes close to worthless.(Miliband, 2011)
