I understand the Campaign for Nuclear Disarmament submitted an application to use Parliament Square for their 24 January 2015 'Wrap up Trident' protest on 24 October 2014, which had agreement from Westminster City Council, the Metropolitan Police and Transport for London. I understand subsequent communications with the GLA did not indicate that there would be a problem in using Parliament Square in principle. However, on 5 January 2015 the GLA refused permission to use Parliament Square. I understand the GLA's justification for withdrawing permission for CND to use Parliament Square referenced another group's actions. I also understand the GLA did not attend a meeting arranged by the Metropolitan Police involving representatives from TfL, CND and Westminster City Council to resolve the problem of using Parliament Square. Please explain why the GLA took such an unhelpful approach to the 24 January 'Wrap up Trident' protest organised by the Campaign for Nuclear Disarmament?
