ProLife Alliance (PLA) or simply ProLife, was an anti-abortion, single-issue political party that was active in the United Kingdom from 1996 to 2004. Since that time it has continued as an advocacy group. It is opposed to any form of euthanasia and opposes human cloning, abortion and experiments on human embryos. It supports and guaranteed maternity and paternity leave. Its leader is Dominica Roberts.
The Pro-Life Alliance was founded by two anti-abortion activists, Josephine Quintavalle and her son Bruno Quintavalle. They contested the 1997 general election, bringing about litigation against the BBC over the latter's refusal to screen the PLA's party political broadcast. The party contested 56 of the 659 constituencies and attracted a total of 19,332 votes. It gained over 1% of the vote in only five constituencies in England and Wales, although did slightly better in Scotland, where it averaged 1.5% of the vote and secured over 2% in three seats. Its vote share declined further in the 1999 Scottish Parliamentary elections, 2001 general election, and 2004 European Parliament election. It disbanded in 2004. Much of its support transferred to the Christian Peoples Alliance, a minor Christian democratic movement.
