Previous election results

There are several political parties in the UK, however, the two that have dominated the political arena in the 20th and 21st century are the Conservatives and Labour.

How does voting work in the UK?

Voters in 650 constituencies across the UK will elect members of parliament to the lower chamber, the House of Commons, via the first-past-the-post system. To win each constituency and gain a seat in the House, candidates need to receive more votes than any of their competitors.

A party needs to win at least 50 percent of the seats – 326 – to secure a majority in the House of Commons and be asked to form a government by the monarch, King Charles III. The members of parliament’s upper chamber, the House of Lords, are appointed rather than elected.

If no party wins a majority, there is a hung parliament.

The UK’s current parliament

Before parliament closed on May 30, the House of Commons was represented by 13 parties and 17 independents, including:

• The Conservatives – 344 seats (52.9 percent)
• Labour – 205 seats (31.5 percent)
• The Scottish National Party (SNP) – 43 seats (6.6 percent)
• The Liberal Democrats – 15 seats (2.3 percent)

The remaining 43 seats were held by nine other parties and independents.
