Electoral process for parliament
First-past-the-post is used to elect MPs to the House of Commons and for local elections in England and Wales. the UK or local authority is divided into numerous voting areas i.e. constituencies . At a general or local election, voters put a cross (X) next to the candidate they like.
Ballot papers are then counted and the candidate that has received the most votes is elected to represent the constituency.

Alternative Vote
The Alternative Vote is used to elect the majority of chairs of select committees in the House of Commons. voters rank candidates in order of preference by marking 1, 2, 3 and so on next to names of candidates on a ballot paper. A voter can rank as many or as few candidates as they like or just vote for one candidate.
If no candidate hits the 50% mark the candidate with the lowest votes are eliminated. the second highest voted will then be added to the other candidates If not, the process of elimination and reallocation of preference votes is repeated until one candidate has more votes than the other remaining candidates put together, and is then elected.
