Two government advertisements in Britain have been banned because of overstatement.

The ads, to do with climate change, were banned by Britain's advertising watchdog, which said 939 complaints had been received over forecasts made in them.

The two government adverts accused of overstatement of the threat from climate change, featured nursery rhymes, including "Jack and Jill," to highlight the impact of global warming.

The copy on the Jack and Jill ad read: "Jack and Jill went up the hill to fetch a pail of water. There was none as extreme weather due to climate change had caused a drought."

The advert, commissioned by the Department of Energy and Climate Change, also said: "Extreme weather conditions such as flooding, heat waves and storms will become more frequent and intense."

The Advertising Standards Authority said the ad had exaggerated the risk of climate change and needed to make clearer the nature of the prediction.
