I am afraid that I do not agree with your views on Proportional Representation, and fully support First Past the Post (FPTP). This tried and tested system ensures stability and clear governance, preventing disproportionate influence by minority parties with minimal public support, who typically end up holding the balance of power in PR systems.
The system is clearly well established and understood by voters, and also provides a very clear link between constituents and their representatives in Parliament.
More often than not, FPTP results in a Government with a working majority in Parliament, making decisive government possible. It allows the formation of a clear opposition that can provide an alternative to, and a check on, the Government of the day. The Government therefore has no plans to change the voting system for elections to the House of Commons.
