Leader of the Liberal Party (UK)

When a new leader was required, with the party in government, the monarch selected him by appointing someone as prime minister.

However, in 1916 David Lloyd George, with the support of a minority of the Liberal MPs, formed a coalition government.

From 1919 onward, the Chairman of the Liberal Parliamentary Party, elected by MPs, functioned as the leader in the House of Commons.

In 1931 Lloyd George was leader in the House of Commons, but he was ill when negotiations led to the formation of the National Government.

This was the same system as that used for the last MP only contested leadership election in 1967, when Jeremy Thorpe became leader after a vote split between three candidates of 6-3-3.
