BP profits double to $6.2bn, fuelling calls for energy windfall tax

Results are obscene', say unions, after soaring oil and gas prices help company to beat forecasts

BP's profits more than doubled to $6.2bn (5bn) in the first three months of the year, the highest quarterly profit in more than a decade, helped by soaring oil and gas prices.

Analysts had expected a figure of $4.5bn and the higher profit has renewed calls by campaigners for a windfall tax on oil and gas companies.
