A former city Minister called for an investigation of the private equity company, owned by Monarch.
Greybull Capital 150 for loans to the airline is owed aboutÂ£, but as a preferred creditor, it will be primarily repaid if assets are sold, such as airport slots.
Lord Myners, a Labour peer, called for an investigation into whether this is a matter of “fraudulent-favoured-nation treatment”.
Grey bull, said Monarch’s collapse was outside of his control.
The company bought the airline three years ago, and had tried, but could not have failed to find a buyer for you in the months before the Luton-based company.
A spokesman said: “grey bull’s involvement with Monarch since 2014, the flies and their employees in the work for three years, when no other rescue deal was on the table.
“Grey bull significant capital to Monarch and do not receive dividends, interest or any repayments of their loans.”
Lord Myners told colleagues he wanted to investigate the competent authorities, the private-equity firm action.
Aviation minister, Mr Callanan, said the monarch had to the administrators to report, within three months the actions of the Directors.
The Tory front-Bencher colleagues said: “If there is any traded a proof of the Directors wrong, we will not hesitate to take action against them.”
The rise and fall of Monarch
Four reasons why the Monarch failed
The shadow transport Secretary, Andy McDonald Monarch collapsed, said because of a “litany of errors” by the government and the Civil Aviation Authority, as well as the organization as a donor and Advisor.
The House of Commons transport committee would keep said a “rigorous investigation” in Monarch collapse, transport Secretary Chris Grayling.
To avoid reforms, a repeat of the Monarch would collapse also considered, he told MPs.
Around 80,000 Monarch passengers were said to be brought to the UK on rescue flights, Mr Grayling.
To compensate for the cost to come home to, to discuss all of the 110,000 Monarch customers with credit-and debit-card companies, he added.
Monarch’s demise has laid off 1,800 employees.
The British Airline Pilots’ Association and the Unite union have both criticized the Monarch for his handling of staff redundancies in the last week, and said they would take measures to ensure that employees were paid correctly.
