35 years on from the Limehouse Declaration and the launch of the SDP it’s easy to see the similarities. We have a Labour Party with a very left wing leader pushing ideologically driven policies and zero prospect of winning the next election. And we have a Conservative Party which is pursuing harsh economic policies at home and is split down the middle over the UK’s relationship with the EU.
But if there are similarities with 1981 there are even more differences. Britain is now a very different place socially and economically. It is much more ethnically diverse, particularly in the large cities. It is far less deferential and far fewer people have a strong party loyalty. It is also much more affluent – the average household is now earns twice as much as it did in 1981 – and unemployment and inflation are both much lower.
