The battle for the future of Origin Energy, one of Australia’s biggest energy companies, will be extended until early next month after takeover bidders lodged a revised offer on the eve of Thursday’s vote.

Canadian investor group Brookfield and its US-based partner EIG had offered shareholders the equivalent of $9.43 a share, valuing Origin at about $20bn.
