Answer:
One example of a sanction that the UK had in the past is the economic sanctions against Rhodesia (now Zimbabwe) in the 1960s and 1970s. The UK, along with other Western countries, imposed economic sanctions on Rhodesia to pressure its government to end its unilateral declaration of independence from the UK and to move towards majority rule. These sanctions included restrictions on trade, investment, and travel. The sanctions were effective in isolating Rhodesia and contributed to the end of white minority rule in the country.
