UK - Markets in the UK and US have tumbled with analysts attributing the drop to growing fears of a global slowdown. The FTSE 100 saw its worst day of trading this year, closing 2% lower. In the US, the three main indexes ended between 1.9% and 2.5% lower. The falls came after figures showed eurozone manufacturing growing at its weakest pace in five years in March. Combined with the Federal Reserve's cautious tone on interest rates earlier this week, investors took fright. The Dow Jones Index fell 1.8%, the S&P 500 dropped 1.9% and the Nasdaq lost 2.5%, marking the worst performance for all three indexes in over three months. "The problem right now is that investors are willing to be paid less to wait longer - an indication that they don't have much confidence in the long term outlook for the US economy," says BBC New York business correspondent Michelle Fleury.
