Tim Martin, chairman of JD Wetherspoon, has again taken advantage of the company’s weakened share price, investing almost £1m in the stock for the second day running. The founder of the high street pub group this morning bought 315,000 shares at 310.703p. The purchase takes Martin’s holdings to 32.8 million shares – 23.23% of the company – which at this morning’s share price of 309p, equates to £101.3m. Yesterday Martin invested almost £1m in acquiring 297,127 shares at 333.88p.
