In 1929 my great-grandfather Isaac Foot introduced one of the first legal aid acts in Parliament, the Poor Prisoners Defence Act. He was a solicitor in Plymouth as well as the Liberal MP for Bodmin, and one of his clients, a poor girl, was facing a murder charge with no financial support in the magistrates court. ‘A prisoner who is without means,’ he said, ‘ought to be in no worse position to establish his innocence than a prisoner who is able to pay.’
