This diary is from a collection of the papers of William George, David Lloyd George's brother, which was purchased by the library in 1989. This important archive contains over 3000 letters by Lloyd George to his brother, as well as a series of 11 diaries that he kept during the early years of his political career.
The diary from 1886 contains an account of his personal life and his political career. It describes his first public speech - in Blaenau Ffestiniog on 12 February - and describes his political activities and ambitions in some detail. There are also a few interesting references to his courtship of Margaret Owen from Mynydd Ednyfed, Cricieth, who later became his wife.
You can view the catalogue records for the rest of the Lloyd George diaries on NLW Archives and Manucsripts.
