The horrific terrorist attack that took place in Manchester yesterday will have caused significant fear and concern in communities across the UK, including here in London. Yet at a time when we want to be deploying every available officer to ensure the safety of those communities, we are instead having to plan for a gathering of more than 1,000 people in Trafalgar Square on Saturday in support of a terrorist organisation. By choosing to encourage mass law breaking on this scale, Defend Our Juries are drawing resources away from the communities of London at a time when they are needed most. We urge them to do the responsible thing and delay or cancel their plans.
