In May, Thomas Cook reported in half-year results that it had a net debt burden of 1.25 billion pounds. It said political uncertainty related to Britain’s departure from the European Union had led to softer demand for summer holidays.

A spokesman for RBS, a lender to Thomas Cook, said it “has provided considerable support” to the tour operator over years and “continues to work with all parties to try and find a resolution to the funding and liquidity shortfall.”
