Announcing his return to work just six short weeks since taking leave on medical advice, Lloyds boss Antonio Horta-Osorio celebrated his recovery with the purchase of $226,962-worth of shares in the part-nationalised lender. The director, who was signed off sick with extreme fatigue and sleep deprivation, bought up 150,000 American depositary receipts (ADR), equivalent to 600,000 ordinary shares, at $1.51308, or around 97p, each. Each ADR represents four ordinary shares, meaning Horta-Osorio paid about 24.25p per share, very close to the prevailing share price in London. In a surprise move, it was decided at a Lloyds board meeting on Wednesday to allow the Portuguese workaholic to return to his post in January, following an independent assessment of his health. When he took leave in early November, the company said he would return to his post by the end of 2011, but there was a large amount of scepticism in City circles over whether he would ever regain his place in the hot seat. Some observers doubted whether he would be able to give up a perceived compulsion to micro-manage.Since the decision was made, Horta-Osorio has been decribed by the firm as being "upbeat and eager" to get back to the job, while humble about what has happened. This is his third share purchase this year, and brings his total purchases for 2011 to 900,000 shares. Land Securities Chief Executive tops up stake in firm Chief Executive of Land Securities Group, Francis Salway, bought up £198,505-worth of shares in the real estate investment trust. In November the property giant reported a rise in profits in the first half, driven mainly by increased rental income. Speaking at the time Salway, 53, said his firm was "alive to the potential effects of economic uncertainty and changeable sentiment in capital markets"."We have consistently stated that we did not expect to see a straight-line recovery in our market, rather that it would be interspersed with ripples and we see no reason to adjust this outlook," he added. The director, who joined the group in October 2000 and was appointed to the board a year later, bought the shares at 620.00p each. The company has lost 6.47% on its share price over the past year and 9.79% in the last month.
