Queen Elizabeth II is lying in state at the Palace of Westminster ahead of her state funeral on Monday, September 19.

Mourners have been queuing from Southwark Park to pay tribute to the late queen before public viewing opens at 5pm on Wednesday, September 14.

Members of the public will be able to pay their respects at her coffin 24 hours a day until 6.30am on Monday.

There are strict rules on bags in place and those wishing to visit Westminster Hall are urged to plan ahead.

Here is a list of the banned items you should be aware of if you're planning to pay your respects to the late monarch this week.

What you should and should not bring as the Queen lies in state

The latest government advice says that you are only allowed to bring one small bag per person into the Palace of Westminster.

The bag must be smaller than 40cm x 30cm x 20cm, with one simple opening or zip so that you can move quickly through the security check.

If you have to bring a larger bag, you will need to leave it in the bag drop facility which Stewards will direct you to before you enter the security search point.

The government recommends that you bring food and drinks to consume in the queue, a mobile phone charger, any essential medication and equipment and suitable clothing for all weather conditions.

What does lying in state mean?

Lying in state refers to the formal occasion when a coffin is placed on view to allow the public to pay their respects before a funeral service.

Lying in state is given to the Sovereign, as Head of State, the current or past Queen Consort and sometimes former Prime Ministers.

The last lying in state was the Queen Mother in 2002. An estimated 200,000 people visited the Queen Mother during this time.

What happens during a lying in state?

In the lying in state period, the deceased’s coffin will rest on a raised platform in the middle of Westminster Hall.

Each corner of the platform will be guarded around the clock by units from the Sovereign's Bodyguard, Foot Guards or the Household Cavalry Mounted Regiment.

Members of the public are free to file past the platform and pay their respects.
