Will my AS economics result be a problem for getting offers?

I'm the midst of my AS exams, and next year I'll hope to be applying to do economics at university. I'm taking law, politics and economics to A2, and in my AS' I'll be expecting high A's in law and politics, but I'm slightly concerned about economics, after a time-based disaster on Unit One.. Most of the unis I'd want to apply to require AAA-AAB entry requirements. Will I be held back on getting offers if I only get a B in economics? And if next year I apply to a uni with AAB requirements (Lancaster, Loughborough), is it likely they'll require one of the A's to be in economics?
Thanks TSR. 😊
