NEWPORT County AFC came from behind to seal all three points with a dramatic 92nd minute winner from substitute Ben Swallow.
Southport started superbly and could have led by more than one goal at the break after Chris Lever had scored from the penalty spot on 18 minutes.
But County felt they should have had at least one spot kick of their own in a frantic first 45 minutes and they battled back superbly after the break.
Top scorer Aaron O'Connor levelled with his eighth goal of the season 14 minutes from time before sub Swallow sent the Rodney Parade crowd into raptures with a left foot screamer at the death.
The Exiles remain top of the Blue Square Bet Premier league and travel to AFC Telford on Tuesday night.
