Italy has reacted angrily to a Swedish TV advert which disparages Prime Minister Silvio Berlusconi's relationship with the media. The Italian foreign ministry summoned Sweden's ambassador to complain about the spot for Sveriges Television (SVT). In it, SVT describes itself as a "free" TV channel, in contrast to Italy where Mr Berlusconi "controls 90% of the national TV channels". The state-funded station said the ad highlighted its own independence. "Our ambassador, Steggan Wrigstad, was summoned and the Italian government complained about the ad," Swedish foreign ministry spokeswoman Asa Arvidson told the BBC's news website.
