Xstrata has been given three weeks to “put up or shut up” on its proposal to merge with rival miner Anglo American by the panel that oversees M&A in the UK. Anglo American approached the Takeover Panel on Tuesday to force Xstrata to make a formal offer or walk away for six months. The panel has now set a deadline of Oct 20 for the Swiss miner’s proposal for an all-share merger to create a mining group with a market cap of $68bn.
