The Australian Competition and Consumer Commission (ACCC) has delayed its decision on the proposed sale of Pick n Pay-owned supermarket chain Franklins to Metcash.

The announcement, which was due to be released today, has been pushed back until 18 November.

The A$215m (US$203.9m) deal has faced close ACCC scrutiny as the competition watchdog is concerned that the deal would mean Metcash would have "significantly greater unilateral market power".

A Pick n Pay spokesperson said that it knew of the postponement "some time back", but would not be drawn into the reasons behind the delay.
