Brits have been told not to set off to queue for the Queen's lying-in-state - with the line set to close imminently as those at the end face a 13.5 hour wait.
The government is monitoring the situation and will provide an official cut-off point for people hoping to join, with public viewing set to close at 6.30am tomorrow.
A minute's silence is scheduled as mourners face their last chance to see the Queen's coffin lying in state.
