Troubled Japanese fashion giant, Fast Retailing Co Ltd, on Tuesday said it would raise its UK subsidiary's capital by £20 million to boost its finances and help fund expansion. The company said in a statement it planned to strengthen the capital of its wholly-owned UK subsidiary to £30m on May 2, just weeks after president, Tadashi Yanai, said he wants to open 50 Uniqlo shops in the UK by 2005.
