What a larger Royal Navy could and could not cover

What operational problem was a larger frigate force meant to solve for the Royal Navy?

It would strengthen global presence and anti-submarine warfare while preserving scarce air-defence ships and other high-end units for carrier and amphibious groups.

A government decision should be assessed by the capabilities it buys rather than accepted or rejected on partisan identity alone. The Royal Navy still had to balance two carriers, an amphibious group, a limited number of air-defence destroyers, and standing deployments. Additional frigates would strengthen forward presence and anti-submarine warfare, two roles in which Britain expected to make a distinctive contribution. The fleet could not maximize every mission, and submarine production was constrained by the capacity of a single yard. More hulls therefore improved resilience only when matched by clear priorities, industrial throughput, and enough trained personnel to crew them.
