Prime Minister Gordon Brown’s proposal to boost the tax rate to 50 percent from 40 percent on income above 150,000 pounds ($220,000) pushed headlines about “class warfare” onto the front pages of the capital’s newspapers. It also prompted predictions from business groups that it would undermine the U.K.’s competitiveness and lead to an exodus of financial talent. Brown was portrayed as Vladimir Lenin in a cartoon on Page One of the Daily Telegraph.

The income-tax change, set to take effect next year, would give the U.K. a higher top rate than Spain, Italy, Germany, France and the U.S., according to KPMG, the accounting firm. Among the 30 members of the Organization for Economic Co- operation and Development, the country would jump to seventh from 19th in the rankings of tax rates, accounting firm Ernst & Young said.
