Caerphilly MP Wayne David has given a special lecture in Parliament on the first conscientious objector to become an MP.
Morgan Jones was the Labour MP for Caerphilly between 1921 and 1939 and refused to fight in World War One, citing his socialist politics as to why he opposed the war.
Mr David said: “Morgan Jones is truly one of the unsung heroes of British and Welsh politics. After opposing the First World War, he was imprisoned and suffered because of his principles. He then became the first conscientious objector to be elected to Parliament.
“In Parliament, he was a junior education minister and he pioneered the idea of comprehensive education. He was also a strong advocate of Welsh devolution who first led the campaign for Wales to have its own secretary of state.
“But above all, he never forgot that his first duty was to his constituents in the Rhymney Valley.”
