The founder of the Carphone Warehouse (AOL, TalkTalk), Charles Dunstone, has confirmed that a bid of £550m is being made for rival ISP Tiscali UK. Tiscali is known to be reviewing any interest today and others may well have lodged their own offers, although there are no further details at present. Typically the offer only appears to be for Tiscali’s UK wing and not the group as a whole, which would have included its Italian division. More @ Techwatch.
