One estimate says people could wait 12 hours to pay respects at Westminster Hall in London
Officials have set out formal plans for the public to pay their respects to the Queen as her coffin lies in state inside the UK parliamentary grounds, amid warnings that those wishing to do so might have to queue overnight.
The Queen’s coffin will be placed in Westminster Hall, the 11th-century building which is the oldest in the parliamentary estate, from 5pm on Wednesday until 6.30am on the day of the funeral, next Monday.
