Brendan Barber: 50p tax plea is 'unattractive'
More than 500 small and medium-sized business leaders have called for the 50p top rate of tax to be scrapped in the Budget.
In a letter to The Daily Telegraph, they claim the tax is reducing government income, and damaging the economy.
Any income over £150,000 is currently taxed at 50%.
The Chancellor has said he wants the measure to be temporary.
Brendan Barber, the general secretary of the TUC, said there was no evidence to support the call to scrap the rate.
