Dover restored their lead at the top of the Ryman League Premier Division to 20 points with a 4-1 win at Harlow on Saturday.

Lee Browning put Andy Hessenthaler's men ahead after 14 minutes and then added the second having also hit the woodwork in the opening half-hour.

Ricci Crace headed in for the home side early in the second half but Frannie Collin netted two second-half penalties to take his league tally to 18 for the campaign and seal the win.

Nearest rivals Staines were held to a goalless draw at Maidstone.

Chances fell to both sides in the opening half-hour but Jay Saunders and Lloyd Blackman missed out for the Stones while Staines' Lewis Cook twice fluffed his lines in front of goal.

Blackman again went close before the end while Elliot Bradbrook had a header saved late on.

Tonbridge's play-off hopes suffered a setback when they lost 3-1 at home to Sutton.

The game came to life just before half-time when Sutton boss Paul Doswell was sent-off by the referee after a touchline incident.

It sparked his side into action, however, as a Leon Legge own goal put them in front in the 44th minute.

Sutton made it 2-0 with 13 minutes left when Chukki Eribenne set up Craig Dundas to score, and Gavin McCallum's close-range effort wrapped the game up moments later.

Tonbridge pulled a consolation goal back late on when Legge took advantage of a defensive mix-up.

Improving Margate boosted their survival hopes with a comprehensive 3-1 win over Boreham Wood.

Margate went ahead early in the second half through Dan Young and added a second through Ryan Peters' penalty.

Boreham Wood pulled one back when Sean Sonner headed in but Joe Healey claimed Margate's third straight after to end any hopes of a comeback.

Ramsgate remain deep in relegation trouble after a 2-0 defeat at Canvey Island.

Leon Gordon put the Essex side ahead after Rams keeper Jamie Turner had initally saved his first effort in the 41st minute and Craig Davidson doubled their lead just before half-time from the penalty spot.

Both sides were reduced to 10 men with Ramsgate's Des Byrne and Kevin Dobinson of Canvey red carded.

Dartford's long run without conceding a league goal came to an end when they lost 1-0 at Ashford Town (Middx).

Lee Noble wasted Dartford's best chance in the first half and they were made to pay when Byron Harrison scored early in the second half - the first league goal conceded by the Darts since December 27.
