Police are allowing female protesters to remain in St Paul's and are no longer present within the cathedral, a spokesman for City of London police said.
Staff at the cathedral told police they were happy for the activists to remain and so officers left the building but maintained a presence outside to police the protest there, the spokesman said.
Protesters opened a large banner on the cathedral steps with the slogan "throw the money-changers out of the temple". The action came as the anti-greed group marks the anniversary of its now dismantled protest camp outside the cathedral.
