Mourners will be able to file past the coffin of Britain's late Queen Elizabeth in a round-the-clock lying-in-state from Wednesday evening to early on the day of her funeral, with authorities preparing for a huge turnout.

Hundreds of thousands of people are expected to pay their respects to Britain's longest-reigning monarch ahead of her state funeral on Sept. 19, which will be attended by world leaders.
