The union that represents Thomas Cook shop and head office staff is to discuss the collapse of the company with the MP leading a probe into the failure.

Transport Salaried Staffs’ Association Manuel Cortes is due to meet the chair of the Commons business committee Rachel Reeves MP this afternoon (Monday).

The committee has agreed to set up an investigation into the collapse of the firm last month after Cortes wrote to Reeves calling for an urgent inquiry.

Cortes has since called for the resignation of business secretary Andrea Leadsom over her handling of the crisis.

He has also demanded that Reeves brings ministers and former Thomas Cook CEO Peter Fankhauser, before the committee.

Speaking ahead of the meeting in Parliament, Cortes said: “It’s crucial that the business committee use every lever at their disposal to get to the bottom of why Thomas Cook was allowed to go under.

“Everything points to negligence on the part of this Tory government and Leadsom in particular. She has admitted failing to hold a single meeting with Thomas Cook bosses in the days leading to the collapse.

“There are other questions to answer about how much the government knew about possible financial assistance from European governments.

“Now she, and others, must be held accountable in Parliament for this dereliction of duty. Thomas Cook staff, our members, and tens of thousands of holidaymakers must have answers.”
