Bain Capital, the owner of the Domino’s Pizza chain, is believed to be one of the possible bidders for Diageo’s Burger King empire.

Diageo said it has received “some approaches” for Burger King but declined to confirm if Bain Capital, Blackstone Group and Texas Pacific Group were on the list.

Blackstone, an American private investment firm, owns the Savoy Group of Hotels in London and has a stake in Host Marriott. Texas Pacific is one of the backers of Punch Group.

Diageo said there had been approaches for Burger King, which is likely to fetch around $2bn, “but we can’t give the full details since it could just lead to more speculation.”

The group said it could not act on these offers as it has yet to finalise how the planned separation of Burger King from Diageo will be carried out.

It said: “We’re still evaluating the best way to separate the business. It could be via IPO, MBO or an outright sale. We haven’t announced what options we want to go for.”
