Last month it was revealed that property tycoon Nick Candy was weighing up whether to make an offer to buy THG in a deal worth £1.4bn.
The proposed move by Mr Candy, who is married to former Neighbours actor Holly Vallance, was announced on the same day as a £2.07bn takeover bid from two investment companies was rejected by the Manchester-headquartered group.
Belerion Capital and King Street Capital, as well as Mr Candy's Candy Ventures, have until Thursday, June 16, to make a formal bid or walk away.
