"Rio Tinto is right to play the Oliver Twist card and ask for more from bidder BHP Billiton. This is the bid that has everything: it's audacious, it's worth megabucks (the combined group would be valued at $350bn) and it features an intriguing intervention from a Chinese state investor - one of the big themes of this year. Best of all, it is shaping up to be a real ding-dong battle."
