Children march during an anti-abortion demonstration in central London October 27, 2007. The 1967 Abortion Act, which marks its 40th anniversary on Saturday, allows terminations to be carried out up to 24 weeks after conception. However anti-abortion campaigners argue that medical advances mean that babies have a better chance of survival at 24 weeks than in the past, and say the upper limit should now be reduced.
