It was not all plain sailing for leaders Leicester, who were behind until the hour-mark against Blackpool after David Goodwillie scored his first goal for the Lancashire club four minutes before half-time.
Nigel Pearson's side, though, hit back as French winger Riyad Mahrez equalised with a fine strike from 20 yards out and then Wes Morgan and evergreen former Blackpool striker Kevin Phillips struck in the last 10 minutes to secure a fourth consecutive victory.
The prolific Ross McCormack put Leeds in front after 27 minutes, but Jason Pearce's own-goal ensured Sean Dyche's side were level at half-time. Scott Arfield consigned Leeds to a third defeat in a row with a strike into the far corner of the net to pile more pressure on Brian McDermott.
Uwe Rosler's side move above Nottingham Forest, who were held to a goalless draw by Doncaster Rovers at the City Ground and have now failed to win in seven games, while Brighton and Hove Albion are just a point behind Billy Davies' charges after Will Buckley scored both goals in a 2-0 win at Bolton Wanderers.
The point for Charlton, which was Jose Riga's second in as many games since he replaced Chris Powell as manager, was enough to move them off the bottom on goal difference ahead of Yeovil and Barnsley.
In the other games to be played on Saturday, Sheffield Wednesday beat Birmingham City 4-1 and there were no goals in Middlesbrough's clash at Bournemouth.
