Vincent Cable may not be asked by the BBC to comment on this policy

Vincent Cable is the BBC's favourite expert economist politician, always on-hand with his BBC approved views. However his piece in today's Independent that includes this thought:

"There are demands for a windfall tax. But this largely misses the point. The headline profits usually relate to global operations, of which only a modest part is in the UK. Even if there were a large UK-based windfall tax, the same logic would apply to wheat farmers, who have also benefited from rising world prices. What is more, all these arguments for a windfall tax ignore the inconvenient truth that North Sea producers already face a windfall tax."

Something tells me that the BBC will not be asking Vincent Cable on to discuss this policy as the BBC have already decided how they feel about a "windfall tax".
