Zafar Khan

Khan was succeeded as chief financial office by Emma Mercer, who had worked for Carillion in a decade-long career. Khan will continue to receive his salary of £425,000 until July 2018.

Khan was one of six Carillion directors who appeared before House of Commons select committee hearings on 6 February 2018. Rachel Reeves, chair of the business committee, suggested Khan "fell asleep at the wheel" during his tenure. Khan told the committee he thought he had "spooked the board with results of the contract review".

On 17 March 2018, it was reported that the Financial Reporting Council's conduct committee would announce an investigation into the conduct of Richard Adam and Zafar Khan (both members of the Institute of Chartered Accountants in England and Wales). The investigation, confirmed on 19 March 2018, would focus on the preparation and approval of Carillion's financial reports for 2014, 2015 and 2016, and the six months to 30 June 2017, as well as provision of other financial information from 2014 to 2017.

Khan was criticised in the final report of the Parliamentary inquiry into the collapse of Carillion, published on 16 May 2018. The report concluded:

Zafar Iqbal Khan (born August 1968), is a British accountant and businessman, and was the finance director of Carillion from 1 January to 11 September 2017.

Khan followed Richard Adam from Associated British Ports joining Carillon in 2011, as finance director for the Middle East and North Africa business, and was its group financial controller from 2013. Khan was the finance director of Carillion from August 2016 to 11 September 2017 (and a main board director from 1 January to 11 September 2017), and succeeded "long-serving" Richard Adam, who had been finance director since 2007. Khan "helped unearth major problems" including a "£845m black hole".
