Why these graphic posters were outside Downing Street

• Bpas and other supporting organisations delivering the petition outside Downing Street

Britain's largest abortion provider, Bpas, delivered a 100,000-strong petition calling on the government to introduce buffer zones around termination clinics to Downing Street on Wednesday.

The call was made in the wake of increasing protests outside clinics by anti-abortion groups, notably Abort 67, whose members are known for using large posters featuring graphic images of aborted foetuses and filming demonstrations.

The group normally spends Wednesday campaigning outside Blackfriars medical practice, a GP surgery where a clinic offering terminations opened earlier this year, but this week it went to Westminster to counter-protest the Bpas petition.

A source tells i100.co.uk Abort 67 initially went to the wrong place, but once Bpas and the other organisations supporting the campaign to create buffer zones (including the Royal College of Midwives, the Royal College of GPs and Mumsnet) arrived the group quickly moved down Whitehall to stand opposite the gates to Number 10, putting up large graphic banners on the other side of the road.

Abort 67, which also uses paid protesters to stand outside clinics, told i100.co.uk: "Bpas doesn't have a leg to stand on with this buffer zone."
