On 16 December 1998, the government introduced the bill which would have eventually become this Act. MPs from all major parties were permitted a
conscience vote. On 25 January 1999, the Bill passed its third reading in the House of Commons by a vote of 282 to 81, but the House of Lords rejected it once again, this time by a vote of 222 to 146 (a majority of 76). On 19 January 2000, the newly established
Scottish Parliament passed by a vote of 90 to 16 a non-binding motion "that the Parliament endorses the principles of equalising the age of consent for homosexual and heterosexual activity and creating a new criminal offence of breach of trust as set out in the Sexual Offences (Amendment) Bill considered by the UK Parliament in the 1998-99 parliamentary session and agrees that the UK Parliament should consider any Bill introduced in the same terms in the current session". On 28 January 2000, the government reintroduced the bill: on 28 February, the Commons voted 317–117 to grant it a third reading. Since the Commons had passed it in two successive sessions of Parliament, the
Parliament Acts 1911 and 1949 could have been used to enact the bill had the House of Lords not passed it before the end of the session (regardless of whether the Bill had been outright rejected or simply not put up to a vote). The Lords passed the bill at
second reading, but during committee stage, by a vote of 205 to 144 (a majority of 61), they agreed to an amendment which would have maintained the age of consent for anal sex (whether with a male or with a female) at 18. The Government (which is in charge of parliamentary business in both Houses and opposed this change) did not allow the Lords a
third reading vote on the amended bill. At the end of the session, on 30 November 2000, then-Speaker of the House of Commons Michael Martin certified that the procedure set out in the Parliament Acts had been complied with. The bill received royal assent a few hours later, and was enacted as the Sexual Offences (Amendment) Act 2000; its provisions came into force throughout the UK on 8 January 2001. == Aftermath ==
