Interesting comment (although without any details or sources) in the Daily Excess:
After initial meetings with Sullivan and David Gold, Yeung finally went to the St Andrews ground on Tuesday for another round of negotiations that included Karren Brady, the club’s managing director.
She, too, has sold a small percentage of shares to Yeung, who has tried unsuccessfully to buy Reading and Everton. If Yeung were to increase his stake in Birmingham to 30 per cent it would be enough to trigger a bid for complete control.
