Ticket-holders to the London 2012 Olympics have been issued with a list of prohibited and restricted items.

It's a two-page PDF with reasonable airport-style guidelines on the first page (don’t bring sharp objects, alcohol, bottles larger than 100ml and so on) to the more bizarre and slightly innocuous restrictions on page two.

Restricted items include flags larger than 1 metre x 2 metres and flags of other countries not taking part in the Olympic Games.

Unless you own flags from Kosovo, Somaliland, Macau, Kurdistan, Gibraltar, Catalonia or Tibet, assume you're good to go.

LOCOG are also clamping down on ‘ambush marketing’ so items bearing overt “commercial identification” are restricted.

But Lord Coe doesn’t seem to be quite sure what would count as overtly commercial.

In an interview with the BBC’s Today programme he said if you are wearing a T-shirt with the Pepsi logo on the front you will be turned away. But you might just make it in if you’re wearing Nike trainers.

“Excessive amounts of food” are also banned. I'm not sure what constitutes excessive and I'm not sure the 'food police' will either.

The only reasonable restriction on the list are “noisemakers”, not surprisingly given the amount of fuss made over the notorious vuvuzela during the South African World Cup. Plus, they're really annoying.

Full list of items restricted from London 2012 venues:

·         Large flags (bigger than 1 metre x 2 metres), banners and poles.

·         Oversized hats.

·         Large golf-style umbrellas.

·         Large photographic and broadcast equipment over 30cm in length, including tripods and monopods. You cannot use photographic or broadcast equipment for commercial purposes unless you hold media accreditation.

·         Excessive amounts of food.

·         Balls, rackets, frisbees or similar objects or projectiles.

·         Noisemakers such as hunting horns, air horns, klaxons, drums, vuvuzelas and whistles.

·         Any objects or clothing bearing political statements or overt commercial identification intended for ‘ambush marketing’.

·         Flags of countries not participating in the Games (this excludes the flags of nations under the umbrella of a participating country such as England, Scotland and Wales)
