The NSW government is likely to knock back a push to open bars and pubs in the inner city for extended late night trading in the week prior to Mardi Gras.

The appeal to wind back the lock-out laws for the week follows the suspension of the lock-out laws for the one night of Mardi Gras last year.

Christine Forster, the Liberal City of Sydney councillor, and the independent Member for Sydney Alex Greenwich have both called for a suspension of the lock-out laws for the week before Mardi Gras, to help capitalise on the influx of visitors to the city.

But the appeal is likely to fall on deaf ears, with last year's one-night exemption set to be repeated this year.
