First past the post is bad for everyone

Tories (falsely) assume first past the post is a suitable democratic system which will deliver what the people want. But the people rely on being able to use democracy to hold the state to account. If they do not have full democracy this can lead to interventionist governments and despotism. Assuming the Tories are in favour of free markets and against socialism they have made a false assumption in thinking that fptp is suitable... even though pr would (directly) hurt their party. The interests of their party would be served more efficiently with a fully democratic system. It is a false assumption for people on the right (often Tories) to assume that fptp is acceptable.
