The deal already has the backing of rival Lonmin, down 16p at 829p, which owns 28% of Ashanti, but it will need the approval of the Ghanaian government. If it is completed, it means Anglo will have knocked rival Newmont off its perch as the world's biggest gold producer. Shares of Anglo rose 13p to 1097p, partly supported by Merrill Lynch, which rates Anglo a buy and has raised its target price from 1193p to 1317p.
