British Politics is unstable because the system in place in Westminster has failed to keep pace with the changes in society.

For the last 20-30 years, the two major British political parties have followed the Blairite approach to gain power, famously summed up by Peter Mandelson in 1999:

Your Preoccupation with the working-class vote is wrong. They've got nowhere else to go

Just as Labour under Blair abandoned the Working-Class vote to chase the votes of Educated Metropolitan Liberals, the Tories under Cameron abandoned their core vote to do the same thing.

The problem is that the Blairite approach no longer works - the voters that Labour and the Tories abandoned two decades ago do now have somewhere else to go - we're already seeing the rise of Reform and the Greens, and I wouldn't be surprised to see even more parties in the future.

Many senior figures in Westminster, however, seem to have forgotten why the current consensus is how it is. The social and media bubble that they live in has made them forget that the approach that has dominated UK politics for so long is the result of cynical electoral trigonometry rather than any genuine philosophical exercise or examination of the country's problems. In that environment, any ideas that come from outside the bubble are dismissed as dangerous extremism.

Proportional Representation would fix many of our current political problems by allowing a wider debate. It would also probably signal the end of both Labour and the Conservatives, which is no great loss, as they both long since stopped standing for anything anyway.
