Nov 15 (Reuters) - Shareholders of AGL Energy Ltd (AGL) , Australia's top power producer, on Tuesday, went against their board to approve four directors proposed by the company's top shareholder, climate activist and billionaire, Mike Cannon-Brookes.

The appointments follow months of tussling between AGL and Cannon-Brookes' Grok Ventures over control and more influence, which forced the power producer to ditch a planned demerger and accelerate the closure of its coal-fired power plants.

Here are the key events in AGL's battle with its top shareholder so far: March 2021: AGL announces it will split into a bulk power generator and a retail business in a bid to revive its battered shares and lure investors who shun coal. April 2021: AGL Chief Executive Brett Redman resigns just two-and-a-half years into the role and less than a month after the company announced the demerger plans. June 2021: AGL says it expects to split by June 2022 and stop paying special dividends. February 2022: AGL rejects an unsolicited $3.54 billion takeover offer from Cannon-Brookes and Canada's Brookfield Asset Management BAMa.TO , and instead backed its spin-off plan. March 2022: AGL rebuffs a sweetened $4 billion takeover proposal from Cannon-Brookes and Brookfield. May 2022: Cannon-Brookes takes an 11.28% stake in AGL, aimed at blocking the company's proposed demerger.

AGL stands firm by its plan to split. Cannon-Brookes seeks two seats on AGL's board if the planned split fails.

AGL ditches its plan to split, says its chairman and CEO would step down. June 2022: Brookfield Asset Management buys a 2.6% stake in AGL, becoming its No.4 shareholder. September 2022: AGL promotes board member Patricia McKenzie to replace Peter Botten as chair. Cannon-Brookes says the company would be best served by an external appointment.

Cannon-Brookes' Grok Ventures nominates four additional directors to AGL's board.

AGL unveils plans to spend up to A$20 billion on renewable energy by 2036 and bring forward its exit from coal-fired generation by a decade. October 2022: AGL recommends shareholders vote against three of the four directors nominated by Grok Ventures. November 2022: AGL shareholders defy the board and approve all four director nominees proposed by Grok Ventures.
