Sir – Keith Mitchell expresses surprise that campaigns to save libraries are so much stronger than campaigns to protect adult social care and services for young people: but why is this so?

Libraries are able to galvanise support from enough articulate and energetic people to form effective campaigning groups which engage in the political process.

Many beneficiaries of adult social care by their nature tend to be isolated and vulnerable individuals, who are politically weak. They struggle to find a collective voice, with only hard-pressed charities to make their case. Young people are outside the political process, so they need the older generations to fight on their behalf: but how many places are like Wolvercote and Cutteslowe where local adults have banded together to save the services which young people depend upon?
