Christian ’Toto’ Wolff has admitted he might increase his minority stake in the Williams team to 49 per cent in the future.
It emerged last week that, alongside founders and long-time owners Sir Frank Williams and Patrick Head, the stake bought by Austrian entrepreneur Wolff in 2009 was 10 per cent.
"I can confirm it is 10 per cent," he is quoted by the German-language motorline.cc.
"But I have an option to increase my minority stake to a strategic investment."
The publication said Wolff’s share could increase to as much as 49 per cent, also quoting him as saying he would consider exercising the option "in time".
But he rejected British reports that the Oxfordshire based team is in financial trouble and struggling with losses and debt.
"If you look at the last 12 months, 2009 for us was a good and very profitable year," Wolff insisted.
