On another discussion thread somebody pointed out that slavery is illegal in the UK and has been for some time. True enough. On the off-chance that somebody who reads this blog may be in touch with the Home Secretary, here are the facts:
Slavery in Britain has been illegal since Lord Mansfield's decision in the Somersett case in 1772. Slave trade in the British Empire has been illegal since 1807. Slavery in the British Empire has been illegal since 1833. We need another Bill about as much as we need Theresa May.
Maybe that last sentence is a little tactless.
