Allen & Overy (A&O) and Simpson Thacher & Bartlett are among a collection of firms to have advised as Dutch supermarket company Ahold ties up with Belgian rival Delhaize.

Linklaters and Cravath Swaine & Moore acted for Delhaize in a deal that will create a business with a combined revenue of €54.1bn (£38.4bn) in sales.

The all-share merger will form a supermarket chain with operations in the US, Europe and Asia. Ahold will own 61% of the new company.
