The video below features every British general election there has been under HM’s government, starting in 1708 after the Acts of Union between England and Scotland. The video continues until the current most recent election in 2019.  Enjoy!

Additional info and clarifications about the video:

During the period 1708 – 1721, there was no prime minister until Robert Walpole became Britains first PM in 1721. Therefore in this video, this symbol (✓) shows who the largest party is after each election in that time period. Starting with the election of 1722 this symbol (✓) shows who becomes the PM after every general election until the most recent one in 2019.

The video does not show Prime Ministers who were appointed between elections, except if or when they later won or lost an actual General Election.   Example:  Neville Chamberlain never led his party in an election, while Winston Churchill was appointed his successor upon the outbreak of WWII but never won an election until 1951. 

“The Whig Junto” is the name given to the group of leading Whigs who were seen to direct the whig party, during the reign of King William III and Queen Anne.

In the election of 2010, Cameron and Clegg formed the first coalition in British history to be formed directly from an election outcome. After negotiations, Cameron became Prime Minister, and Clegg became Deputy Prime Minister.
