Parliament’s inquiry into Cook’s collapse will continue on Tuesday and Wednesday following criticism of the two former chiefs and accountancy firms PwC and EY.

Fontenla-Novoa was at the helm of the company when it underwent rapid expansion from 2003-2011, with some believing the debt mountain built up during this period contributed to its demise.

Green is under the spotlight for her remuneration package during a two-year period in which she led the operator.

Both former chiefs will give evidence to the government’s Business, Energy and Industrial Strategy Committee on Wednesday. Also present will be Bill Scott, former chief finance officer.

The questioning of the accountancy firms, which will be on Tuesday, follows criticism by the Institute of Directors over accounting methods used at Cook. The IoD has also questioned how directors’ pay and bonuses were calculated on profits that excluded one-off negative items.

Tuesday’s hearing will also receive evidence from Manuel Cortes, general secretary of union TSSA, who will detail the impact of the collapse on workers and consumers.
