Fptp is a monopoly for the Labour party

With a fptp voting system voters are 'required' to be loyal to and vote for the respective parties of the left and the right. If people are not loyal in this way they will lose and suffer either Leftism or Rightism which is not what they (respectively) want. So this form of democratic system requires discipline and loyalty on each side. Since the left is ideologically more collectivist then fptp poses less of a problem for the left. It takes more discipline for Libertarian voters and voters on the right to be loyal to a particular party. This means that it is much easier for the left to prosper in a fptp election. Fptp elections are very difficult for the right to do well in. The right can only succeed under fptp if it is able to make a sufficiently large proportion of the population scared of a Labour victory... sufficiently scared to vote for the Tories. If the right is not able to make people scared of Labour then they will lose. The right will lose under fptp if it cannot terrify people into supporting the dominant party of the right. If people are scared into Tory loyalty by Labour then fptp is equivalent to pr otherwise it is worse (than pr) for the right. If people are not scared (enough) of Labour to vote for the Tories then fptp is bad for the right. For Labour to do well under fptp they need only to not be scary to the general electorate.
