In the UK are held every five years. (The Minister may decide to hold one
after four years, but five years is the maximum.)
Some countries have a system of proportional representation: this means in theory, that a
political party with 30% of the should get 30% of the seats in . In
the UK, the political is different: here the winner takes all. This means that the
person with the most votes in each political area (called a constituency) wins the seat: and the
political which wins a of the seats will the government
on their own. As a result of this system, it is possible for a party to be in with only
40% of the total vote. Some people think this system is unfair.
