Hugh MacKay, the Chief Executive Officer of Europa Oil and Gas, has acquired 545,880 shares in the AIM-listed company, taking his stake to a total of 2.34m. MacKay, who bought the shares at 8.20p a go, spent a total of £44,762 on the purchase. The transaction came just two weeks after the company raised £2.86m after placing 47.69m shares, and a further £1.16m through the open offer of 19.33m shares at the same price of 6p. It has been a fairly turbulent year for the exploration and production company, during which time it has hit a high of 12.28p and a low of 5.88p. Meanwhile, Vedanta Resoures has announced yet more share purchases by Executive Chairman Anil Agarwal. The company announced after the close on Wednesday that he had bought a further £5.35m-worth of shares, taking his total holding to 67.99%, equivalent to 181.31m shares. Indian billionaire Agarwal has significantly upped his stake in recent months, showing his faith in the company as it battled a number of difficulties including shutdowns and local opposition to a new bauxite mine.
