During the
First World War, Clynes was a supporter of British military involvement (in which he differed from
Ramsay MacDonald), and, in 1917, became
Parliamentary Secretary of the Ministry of Food Control in the
Lloyd George coalition government. The next year, he was appointed
Minister of Food Control and, at the
1918 general election, he was returned to Parliament for the
Manchester Platting constituency. In August 1917, three months before the
Balfour Declaration, the Labour Party issued a statement in support of a
Jewish state in Palestine. Clynes spoke in favour of a Jewish state. Clynes became leader of the party in 1921 and led it through its major breakthrough in the
1922 general election. Before that election, Labour only had fifty-two seats in Parliament but, as a result of the election, Labour's total number of seats rose to 142. He was held in considerable respect and affection in the Labour Party and, although lacking the charisma of MacDonald, was a wily operator who believed all resources available should be used to advance the material of the working classes. MacDonald had resigned as Labour leader in 1914, due to his wartime
pacifism, and at the
1918 general election, he lost his seat. He did not return to the
House of Commons for another four years. By that stage, MacDonald's pacifism had been forgiven. When the occupant of the Labour leadership had to be decided on through a vote of Labour parliamentarians, MacDonald narrowly defeated Clynes. Clynes was a critic of government policy towards the Irish population in the years after 1918, and attacked 'a recurring system of coercion' which had left Ireland "more angry and embittered . . . than ever' ==Governmental office==
