"Elsewhere in the mining sector, Xstrata ticked down 19p to £38.33 as market sources suggested that talks with Brazilian suitor Vale were being held up over price. Vale is not said to be keen to offer more than £40 a share, while Glencore, which owns an all-important 35pc stake in Xstrata, is rumoured to want something in the region of £45-£48."
