A British businessman, who was a former contractor for South Africa's ailing power utility Eskom, has been extradited from the UK to face charges of corruption and fraud.

Michael Lomas is accused of taking kickbacks on contracts between his firm, Tubular Construction, and Eskom for work at the Kusile power station, which were worth in excess of 1.5bn rand ($85m: £64m).

"He allegedly manipulated contracts. He was previously arrested, got bail and fled the country to the UK," national police spokesperson Brigadier Athlenda Mathe told AFP.

He has not yet commented on the allegations against him.

Eskom has been beset with corruption allegations and is struggling to recover from years of mismanagement that has led to prolonged blackouts in the country.

Mr Lomas landed at OR Tambo Airport in Johannesburg early on Friday morning. He was in a wheelchair and under heavy police escort.

Ms Mathe told local news website News24 that one of the conditions of the extradition was to have a medical doctor on the plane because of Mr Lomas's poor health.

He is set to be formally charged at Kempton Park Magistrate's Court later on Friday.

The National Prosecuting Authority (NPA) requested Mr Lomas's extradition in 2022, but it was delayed while he lodged an appeal, which was ultimately rejected.

He was accused alongside four other alleged co-conspirators - two senior executives at Eskom and two other businessmen. They were arrested in 2019.

The other four men have been charged with fraud, money laundering and corruption for allegedly taking kickbacks and inflating the cost of the work carried out at Kusile power station.

This was meant to help alleviate South Africa's crippling electricity shortages but the project has been beset by delays and faults, according to AFP.

Mr Mathe said Mr Lomas was a "wanted fugitive" who would be handed over to the Hawks, the police unit that investigates economic crime, corruption and organised crime.

Hawks has been working on this case since 2017, when an employee placed a complaint about one of the tenders.
