At the start of world War I, the Prime Minister was H.H. Asquith. He was replaced on 7th December 1916 by David Lloyd George who remained Prime Minister until 19th October 1922. Britain joined the war in August 1914 and it ended on 11th November 1918.
It's not quite clear what the word 'represent' means in the question, but I'll hazard a guess that the questioner wants to know who was Prime Minister. From 1908-1916 it was Asquith, then from 1916-1922 David Lloyd George. The latter respresented Britain at Versailles.
