I wish to see online, for any past Bill of Parliament, in the House of Commons:
which MPs (in the House of Commons) and which peers (in the House of Lords) voted in favour and in opposition.
For instance, I desire this information for Bills that failed to abolish slavery:
But time was lost during the lengthy inquiries by the privy council committee for trade and plantations (1788) and by the Commons itself (1789-1790), and Wilberforce's motion for abolition was disappointingly defeated by 163 to 88 votes in 1791. In the following year, a compromise was reached in the Commons whereby the trade was to be prohibited from 1796.
These were partial measures which only slightly improved the horrific conditions experienced during the notorious middle passage.
The House of Lords stalled the motion pending its own inquiry, which was eventually allowed to lapse because of the wars against revolutionary France. Wilberforce introduced an abolition motion in most subsequent sessions, and these were occasionally lost by only narrow margins, including by only four votes in 1796, when several supporters had deserted the chamber for the pleasures of the opera house.
and the successful Slave Trade Act 1807:
The effect of Stephen's 1806 act was to reduce the trade by two-thirds, paving the way for the Abolition of the Slave Trade Act in February 1807. The Prime Minister, Lord Grenville, introduced the Slave Trade Abolition Bill in the House of Lords on the 2nd January 1807 when it received a first reading. The House of Lords, voted for the abolition of the slave trade on 5th February by 100 votes to 34; after an impassioned speech by the Prime minister, despite opposition from the West India Lobby. The bill was debated for ten hours in the House of Commons on 23rd February. At 4am the next morning the House voted in favour of the Bill by 283 votes to 16. Finally on 25 March 1807 the Abolition of the Slave Trade Act received its royal assent, abolishing the slave trade in the British colonies and making it illegal to carry enslaved people in British ships.
