rape was extended to include anal rape, previously prosecuted as buggery. This offence was disestablished, as Section 143 - though not given much consideration - legalised anal sex between heterosexual couples, which had been legal between homosexual couples (over the age of 21) since 1967. The age at which homosexual acts were lawful was reduced from 21 years to 18. During the passage of the Bill, MPs considered an amendment to reduce this age to 16 (thereby equating it with the age of consent for heterosexual sex) but the motion was rejected by 27 votes.

The third demonstration was called on 9 October, with police estimating 20,000 to 30,000 people attending, while organisers put the figure at over 100,000. The day ended in a riot in Hyde Park that continued into the evening. Accounts stated that, around 5pm, a confrontation occurred between protesters and police when protesters attempted to bring two sound systems into the park.
