The British economy went through a particularly bad period in the 1970s, with high rates of inflation and devaluation of the currency. Therefore, in the 1980s ,when the Conservative party under Margaret Thatcher was in power,an extensive programme of privatisation was carried out. Many state-owned businesses(such as steel,telecom,gas,aerospace)were turned into private companies.
