The combination would create a retail giant worth between 11 billion pounds ($13.6 billion) and 13 billion pounds which would have more than 581 supermarkets, 700 petrol forecourts and 100 convenience stores in Britain, the newspaper said.

Brothers Zuber and Mohsin Issa and London-based private equity group TDR Capital have owned EG Group together since 2016. They later bought Asda.

Talks over merging the two businesses come ahead of a refinancing of EG Group, which has 7 billion pounds of debt due in 2025, according to the report.

Asda declined to comment on rumour or speculation. TDR Capital did not immediately respond to a request for comment.

The Issa brothers could not immediately be reached for comment.
