ALBANY — Assembly Democrats Monday will introduce legislation increasing the minimum wage from $7.25 to $8.50 an hour, beginning in 2013, a source told The Post tonight.

Starting in 2014 , it would be permanently indexed to the inflation rate.

Senate Republicans — and business leaders — are expected to oppose the measure, a Democratic source said, adding it’s not likely to pass.

Gov. Cuomo has not indicated his position on the proposed law, but said he wants to make the state more business-friendly.
