1. Liberalization
From 1951 to 1997, only two Prime Ministers, Harold Wilson and James Callaghan, were not conservatives. In 1997, however, the Labour Party's Tony Blair was elected and has remained there until today. He is currently serving his third term.
2. Forceful Foreign Policy
Since 1950, Britain has acted quickly and decisively in foreign matters. They supported the US in Korea, invaded Egypt after Nasser nationalized the Suez, forcefully stopped rebellion in Ireland, and supported the US in invading the Middle East after September 11.
3. Fluctuating Economy
Britain's economy from 1950 to 2000 has been a rollercoaster of ups and downs. Discovery of oil in the North Sea boosted the economy but recent tax raises in the 90's and stock market trouble in 2000 have caused problems. Currently, Britain is doing well with its entrance into the European Union and the adoption of the euro.
