Gov. Cuomo issued stricter guidelines Wednesday for campaign spending by independent committees — which would include those used by Mayor de Blasio.

In a speech at Fordham Law School, Cuomo unveiled the rules state agencies will follow to determine if committees like de Blasio’s the Campaign for One New York are truly independent.

They’re not, he said, if “they share an office space, the candidate is appearing at their events.”

Cuomo also proposed spending limits on such groups.
