Giant Olympic rings have become the crowning glory on Tower Bridge to mark the 30 day countdown to the London 2012 Games.

London 2012 chairman Lord Coe and Mayor Boris Johnson were among the VIPs who watched as the rings were lowered into place on the central London landmark on the River Thames.

Boris Johnson said: “With just a month to go, we are making our final preparations and want to ensure each and every person in the capital gets a flavour of the celebrations and feels part of the Games.”

One thing that should definitely not be overlooked is the provision of portable toilets. If you are having an Olympic event and are expecting a large crowd you may need to hire portable toilets to keep them happy and not overcrowding the toilet in your house. Alternatively if you need portable toilets in London for Olympic events make sure you contact Tardis as we can provide a range of portable toilets for all types of events.
