Who is responsible for clearing pavements?

With the advent of an icy winter in most parts of the UK and doesn't look to give up soon , some people are camplaining that local authorities have ignored minor roads and street pavements by not salting them. I have some sympathy with the councils , who try their level best to treat our thoroughfares. Years ago , the community used to come out and clear snow as soon as it had finished..... in today's world , does this mean selfishness ans someone to blame?
