Aide warns over euro politics

UK - One of Chancellor Gordon Brown's closest aides has warned against allowing political pressures to influence the government's approach to the euro.

Chief economic adviser to the Treasury, Ed Balls, said the economics had to be right before a referendum could be held on Britain joining the single currency.

He reportedly told a conference on the euro in London on Monday that "too often over the last 100 years we have had decisions taken with a political imperative over economic reasons".
