The proposals are vital to the heavily indebted company’s short-term future, allowing it to rejig its capital structure and tap equity investors for up to 500 million pounds.

However, the size of the company’s lender group – 300 banks and funds – is working against it. Trying to get all the lenders signed up to the debt deal has been as difficult as herding cats, bankers say.

This will disappoint, as the equity markets have backed a range of weak companies in recent weeks, such as HeidelbergCement and Ladbrokes.
