The UK's renewable power fleet could be dragged into paying a windfall tax on energy profits under plans being considered by government officials, reports say.

Britain's finance minister, chancellor of the exchequer Rishi Sunak, has ordered plans to be drawn up for a mechanism to tax more than £10bn ($12.6bn) of “excess” profitability by power generators as electricity prices are driven up by the cost of gas, said the Financial Times citing unnamed sources.
