Buckles, who was paid a total of £1.2 million in 2012, walked away from the company with a year’s salary of £830,000 and a pension allowance of £332,000.
It came after he was pilloried by MPs following the London 2012 fiasco. The business announced recently that he was leaving to be replaced by Almanza, who only joined G4S as chief financial officer in May.
Its annual general meeting will be the first opportunity for investors to question senior executives over the episode. Buckles had been instrumental in creating the G4S business through the merger of Securicor and the security businesses of Group 4 Falck in 2004.
But the end of his 28-year career was tarnished by the Olympics fiasco, when military personnel had to be drafted in to fill the gap left by G4S’s failure to supply enough staff for the £284m contract.

Hornby is attempting to improve its fortunes after it suffered from poor London 2012 merchandise sales and supply chain problems.

Housebuilders in particular have been benefiting from government measures after the Budget included a new Help to Buy scheme for those struggling to find mortgage deposits, featuring a UK government interest-free loan worth 20 per cent of the value of a new-build house up to £600,000.

Building materials group Wolseley will unveil its latest trading update on Tuesday, with struggles in Europe likely to continue offsetting a better performance from its US arm.
The group, which trades as Plumb Center, Pipe Center and Drain Center in the UK, is expected to do well out of the housing recovery in America, where it has a major presence.
City analysts will also be hoping to hear whether the Funding for Lending and Help to Buy schemes announced in the UK have boosted customer sentiment. The group may also have seen more emergency boiler repair business in Britain and France due to the prolonged cold spell.
Analysts at Numis said that with strong growth in America offset by its European “problem child”, restructuring, particularly in France, could lead to forecast upgrades.
