NSW By-Elections: Labor Claims Marginal Seat Of Gosford

Libs Suffer Massive Swings In Manly And North Shore

Labor has claimed victory in the marginal seat of Gosford in the NSW by-elections on Saturday.

Liesl Tesch -- a five-time paralympian -- will enter NSW state parliament after declaring swings in Labor's favour of 10 per cent.

Earlier in the day, the Liberal party was shamed after the NSW Premier was snapped eating a democracy sausage sans white bread in Manly. But Gladys Berejiklian's naked sausage debacle was the least of the Libs worries after the party was on the wrong side of massive swings in the previously safe seats of Manly and the North Shore.

The Liberal Party has suffered a swing of over 20 per cent on first preference votes in Manly -- Mike Baird's former seat -- to Independent candidate Kathryn Ridge.

It didn't look much better for Felicity Wilson in the North Shore, with a swing against the Liberal part edging over 15 per cent.

Independents were the real winners this weekend as council mergers angered voters, moving them away from the party.
