"On the FTSE 250, the commercial property company Capital & Regional was the focus of some mid-morning speculation. The rumours suggested that the company, which saw its shares soar after it surprised the market with better-than-expected preliminary results on Tuesday, had been, or was likely to be, approached by a suitor. The former chief executive Martin Barber was mooted as a likely bidder, and the company's stock reach an intra-day high of 594.50p, up 41.50p. Later in the day, as the shares shed some gains, sources close to Capital & Regional suggested the contrary, and it is understood that the company has not received any approach yet. The company's stock closed down 0.50p at 552.50p."
