Random Fact of the Day

You can probably guess. Go on. Yes! Rain. We estimate several billion droplets will fall on the capital, mostly wherever you live or work. Some sunny spells are forecast, but with the scarcity of non-sarcastic smiles on Eastenders. Take a brolly, or preferably buy one. BBC Weather.
