Have you ever wanted to just take your trousers off on the Tube and continue about your business? Well then, this is the event for you.

No Trousers Tube Ride does exactly what it says on the tin and is in its ninth year.

Originally starting in New York, the event page on Facebook says it is purely for fun. Last year more than 300 people joined the no-trouser crew.

The event with take place in London this Sunday (January 7) along with other cities around the world. There will even be an after-party to celebrate.

News Shopper:

There are some rules though:

Do not join in if you are not willing to drop your trousers.

You must keep a straight face

The postcode is WC2H 7JR near Leicester Square and you should bring a backpack and an Oyster card/travelcard.

You should wear normal winter clothes (hat, gloves, etc) and everyone should meet before 3pm and be on time.

At 3pm participants will be organised into groups and will walk to nearby stations then when told by a leader they should remove their trousers and put them away.

For the rest of the journey you must sit as you normally would and read or whatever you would normally do.

No inappropriate underwear, no thongs and no mankinis - you don’t want to scare people. The aim is to make them laugh not offend.

This is a safe and fun event so please don’t join in if you’re just going to be inappropriate.
