US trade authorities have asked retail group A&P for more information on its proposed acquisition of fellow retailer Pathmark.

The US Federal Trade Commission has issued a "second request" in connection with the US$1.3bn deal, which was announced last month.

A&P said it would respond to the FTC "in timely fashion". The company added that it still expects to seal the acquisition during the second half of its financial year, which ends in February 2008.

Under the terms of the deal, Pathmark stores will continue to operate under the Pathmark banner. A&P's largest shareholder - The Tengelmann Group - will remain the single largest shareholder of the combined entity.
