An Indonesian magnate is backing a proposal to oust board members of Bumi plc, in one of the dirtiest shareholder battles to hit the London market.
Hashim Djojohadikusumo has voiced his support for the plan set forth by the company's co-founder Nat Rothschild to replace 12 of Bumi's 14 directors.
Rothschild has called an extraordinary shareholders meeting for Thursday to vote on the proposal.
While Bumi has urged shareholders against the vote, Rothschild has an ally in Djojohadikusumo who late last year agreed to join the financier in his efforts to take control of the troubled company.
Djojohadikusumo told the Financial Times he believes a new board would improve governance following long-running company in-fighting.
If the motion is passed, Djojohadikusumo will become a Non-Executive Director of Bumi and Chairman of subsidiary Berau Coal.
Bumi was formed in 2010 when Indonesia's influential Bakrie family reversed their coal mining assets into Rothschild's London-listed cash shell, Vallar.
However, Rothschild and the Bakrres had a falling out following an investigation into financial wrongdoing.
"He was very indignant at how he had been treated and he wanted to size me up," Djojohadikusumo told the UK newspaper of their business relationship.
"Nat's got a lot of emotional investment in this. But I don't. I'm having fun. And hopefully I can make money too."
The tycoon's involvement adds an interesting turn, as he goes against the Bakries in both business and politics.
His brother Prabowo Subianto will go head to head with Bakrie family patriarch Aburizal Bakrie in the initial stages of Indonesia's presidential election, which will go to the polls in 2014.
Djojohadikusumo will also invest "between tens and hundreds of millions of dollars" in Bumi plc if Rothschild's proposal is successful.
The businessman, whose wealth comes from oil and gas investments in Azerbaijan, Kazakhstan and the US, said the dispute has unfairly "damaged the credibility and good name of many Indonesian public companies" that have been "tarred with the same brush".
The Bakries have said Rothschild's hostile attitude is partly to blame for Bumi's problems.
The family's Bakrie Group has put forth a deal to cancel its indirect 23.8% stake in exchange for Bumi plc's 10.3% holding in Asia's biggest thermal coal exporter Bumi Resources.
Bumi Plc would also sell the remaining 18.9% interest it holds in Bumi Resources to the Bakrie Group for $278m.
However, the Bakries warned they would withdraw the offer if shareholders vote for Rothschild's proposal.
In another twist, Indonesian investor Rosan Roeslani has agreed to sell his 10% stake in Bumi.
The move came after Roeslani landed himself in hot water when the UK's Takeover Panel ruled he was part of a 'concert party' with the Bakrie Group and Sami Tan, another Indonesian investor.
The watchdog, which has been urged by investors to intervene in the Bumi dispute, found that together they owned nearly 58% of the voting power of the company. They were told to cut back to under 30%. Consequently, their voting power at Thursday's meeting has been capped at 29.9%.
However, the parties which bought Roeslani's stake will apparently be able to vote, possibly upsetting those who thought Rothschild's position was unassailable.
