A mobile phone texting service that directs users to the nearest public toilet if they are caught short is to be launched, it was announced today.

Anyone needing to spend a penny can text their location to a short number, and then receive a text giving directions to the nearest public convenience, along with opening hours and facilities.

The ingenious concept will become reality in the capital thanks to a competition run by Westminster City Council to come up with ways to make city-life easier.
