List of major liberal parties considered left

Liberalism is frequently associated with centrism; however, especially in countries whose Overton window is to the right, or where the mainstream left–right political spectrum includes liberals and conservatives but not socialists and social democrats, liberals may be considered left-leaning or centre-left as opposed to conservatives. Even in countries where socialist political forces exist significantly, some liberal parties have left-leaning characteristics.
