Hundreds of thousands of people will make their way to London to pay their respects at the Queen's lying in state at Westminster Hall - but there are strict rules on what mourners can bring in with them.

It opened to the public at 5pm on Wednesday, September 24, and it will remain open 24-hours a day until 6.30am on Monday, September 19 - the day of the Her Majesty's funeral.

But as many brave the long queues, they are being urged to get rid of any banned items before they reached the security search point.

Prohibited items will be confiscated and will not be returned. Illegal items will be dealt with by the police.

You must not bring any of the following items:

  • Bags larger than 40cm x 30cm x 20cm in size - bags or rucksacks with expandable compartments, bags or rucksacks with multiple pockets or complex openings, solid-sided bags, or bags on wheels.

  • Food and liquid of any kind - any food or liquids must be consumed in the queue or disposed of before you enter the security search point at the Palace of Westminster.
