An extra £40m is being sought by Bolton-headquartered AO after its share price slumped over the last two days.
Shares in the online electricals retailer have been on a downward spiral since 7am on Monday after it emerged that credit insurer Atradius had cut cover for the firm's suppliers.
Credit insurance protects suppliers against the risk of retailers collapsing before payment for goods is made, and, without this cover in place, suppliers often demand upfront payments, increasing cashflow woes.
