I don't know who used the "giving in" phrase, but the Prime Minister and more to the point, the country, is caught between scientists strongly advising the restrictions continuing despite the economic problems they bring, and businesses - both owners and employees - desperate for their livelihoods.
There is also the very serious problem that the scientists and doctors are warning of, that the spreading disease could be too much for the hospitals to stand, on top of all the parallel problems of deferred treatments for other diseases.
This is happening in many countries, not just the United(?) Kingdom; and no country can live on tick for ever, nor sustain a rampant plague for long.
To be brutally honest there is no clear end in sight for this pandemic, and one epidemiologist interviewed on the radio yesterday said some are warning it could continue for anything up to ten years, though she seemed not to agree with that necessarily.
In any case it will not go away, any more than the bubonic plague that swept across Europe a few times over some hundreds of years has ever gone away. Though at least that is treatable fairly easily - IF caught early enough.
