Marks & Spencer is set to announce a move which will see it secure a further Stg £300 million for shareholders.
The retailer is expected to say it is raising millions of pounds through securitising a number of its stores.
The final value of the securitisation will not be known until the deal is completed, but it is thought it will be about £300 million.
The deal, being carried out through investment bank Morgan Stanley, is thought to be the final part of the group's plan to raise £2 billion to hand back to shareholders early next year.
M&S would not comment on the move, but a spokeswoman said: "In March last year we announced that we were going to restructure the business and return £2 billion to shareholders.
"We have done that by a series of sales and one of those was the sale and lease back of properties."
