A widely-expected poor takeover offer has emerged for Eurasian Natural Resources (ENRC), leaving the stock flat at 217.4p. The real loser in the deal is Kazakhmys (KAZ) which owns 36% of the ferrochrome producer.

Shareholders in the copper producer were also ditching stock after realising that Kazakhmys is unlikely to get a better price for its holding in ENRC. We look at the situation in more detail here, along with a look at Afferro Mining's takeover.
