Only the party of the left can fix first past the post

The generic party of the centre-left under fptp (the Labour party in the UK) have a responsibility to prevent fptp and to introduce pr. The reason for this is that fptp is known to be unfair and to result in tactical voting which undermines democracy and the government. It is the responsibility of the party of the left and not the right to solve these issues because the party of the right is not interested in democracy and government. It is not offensive to the party of the right if the government has a bad reputation. This is why only the party of the left will be able to fix it. It will not get fixed otherwise.
