3 .Although the country's trade deficit was more than￡60 billion in 2006,UK's largest in thepostwar period,officials say the country has nothing to worry about.In fact,Britain does have a world-class pharmaceutical industry and it still makes a small sum from selling arms abroad.It also trades services一accountancy,insurance,banking and advertising.The government believes Britain is on the cutting edge of the knowledge economy.After all,the country of Shakespeare and Words-worth has a literary tradition of which to be proud.Rock'n'roll is an English language medium,and there are billions to be made by their cutting-edge bands.In other words,the creative economy has plenty of strength to carry the British economy.
