AlQa'dah 04, 1436, August 19, 2015, SPA -- Britain's top share index fell on Wednesday, in line with other European equities, dragged lower by commodity stocks and by growing anxiety over China's economy, Reuters reported. The blue-chip FTSE 100 index was down 1.1 percent at 6,453.72 points by 0826 GMT. It closed 0.4 percent lower on Tuesday, more than 8 percent below a record high of 7,122.74 points hit in April. China's stock markets tumbled and soared on Wednesday despite government efforts to stabilise them, although they ended higher after the central bank injected more funds into the financial system for the second day in a row. "The FTSE 100 is actually in negative territory for the year as we speak, and it's quite difficult to see from here what sort of short-term positive impetus the market might take." The index has declined 1.8 percent since the start of the year. The pan-European FTSEurofirst 300 index fell 1.2 percent, also driven lower by worries over China.
