      Lesson details

      Learning outcome

      I can understand how members of parliament are elected.

      Key learning points

      1. First Past the Post (FPTP) is the name for the electoral system used to elect MPs to Westminster.
      2. The number of MPs a party has in parliament rarely matches their popularity.
      3. Fewer people can vote for a party but they can win more seats.

      Keywords

      • First Past the Post - First Past the Post (FPTP) is the name for the electoral system used to elect MPs to Westminster.

      Common misconception

      Winning an election means receiving over half the vote.

      Under the First Past the Post system, a winning candidate must receive more votes than any other candidate. This may not mean receiving over half of the total vote.

      Teacher tip

      You may wish to look at the citizenship lessons that consider elections or collaborate with the citizenship department in your school if you want pupils to explore this further.
