UK seems to have a radical switch in parties in about 15 year cycles since Thatcher, more frequently before that....
Labour didn't receive a majority of the vote (only 34%) but won nearly 2/3 of seats of Parliament, giving them a huge majority.
so even even if they are only in control for 5 years, they can do incredible damage to the UK in that time.
These are descendants of the same geniuses who threw Winston Churchill out. Profoundly defective genes passed along.
