QUOTE:
"The Mayor of London's office said Mayor Boris Johnson was seeking to apply to the High Court over the camp. But the spokesman added he had nothing to do with the police searches.

"The mayor respects the right to demonstrate, however the scale and impact of the protest is now doing considerable damage to the square and preventing its peaceful use by other Londoners - including those who may wish to have an authorised protest," he said.

"As a result he has given GLA officers the authority to apply to the High Court to begin legal proceedings for trespass."

Councillor Colin Barrow, Leader of Westminster City Council, backed the legal action.

"We felt that the hijacking of Parliament Square, one of London's historic public spaces, needed to be brought to an end," he said."
