Zafar Khan voluntarily agreed with the disqualification by the Insolvency Service who are also pursuing cases against other former Carillion directors.

A spokesperson said: “The Insolvency Service, acting on behalf of The Secretary of State for Business and Trade, has accepted a disqualification undertaking from Zafar Iqbal Khan for 11 years for his conduct as a director of Carillion Plc.

“As the litigation against the remaining directors is ongoing, with a trial set to commence the week of 16 October 2023, the Insolvency Service is unable to comment any further.”

Khan stepped down as Carillion’s finance director after nine months in the job shortly before it collapsed in 2018.

He was fined £154,400 last year by watchdogs at the Financial Conduct Authority alongside former chief executive officer Richard Howson (£397,800) and former finance director Richard Adam (£318,000).

The trio are understood to be appealing against the fines.
