Reflections on the Constitution (Works of Harold J. Laski) [PDF ebook] 
The House of Commons, The Cabinet, The Civil Service

This work remains of interest to anyone concerned with Britain’s political institutions and how they might be reformed. Laski was strongly in favour of utilising Britain’s capacity for decisive government to drive through great social reforms. He was still confident that there was a majority will for such change and quite unable to imagine the kind of centralisation that was later to take place in the UK. If Laski is still important it is more for his pluralist views which counsel against such developments, but these lectures are still of interest in showing how a radical reformer could accept and defend established institutions like the House of Commons.
