Battle to beat freeze and keep schools and roads open
Emergency deliveries of salt are en route to councils
The government has pledged to do all it can to keep roads and schools open, amid signs the severe wintry weather is easing slightly.
The Met Office is currently issuing no severe weather warnings, but says snow, ice and low temperatures will continue.
The government has urged schools to make every effort to open to enable pupils to sit exams due this week.
A man has died after falling through ice on the River Tees in Stockton while trying to rescue his dogs.
Local Government Minister Rosie Winterton said great efforts were being made nationally and locally to beat the freeze.
"Council workers are working extremely hard to ensure that as many of the roads are open as possible so that people can get to work, people can, if at all possible, keep their hospital appointments, and that children can get to school. But there's no doubt that it is very difficult," she said.

There will be some further snow overnight, mainly across hilly parts of Wales and northern England, but any disruption is likely to be limited. Many areas will remain icy.
The Met Office says it will stay cold and windy in the week ahead, but with daytime temperatures creeping above freezing a slight thaw can be expected in most areas.
During the cold snap, UK councils have been using about 60,000 tonnes of salt daily and supplies have been running short.
The Highways Agency and local authorities have agreed to cut use of grit and salt by 25%.
The Highways Agency has stopped gritting hard shoulders on motorways in England and councils have had to focus on making sure main routes - public transport routes, and those outside hospitals, schools and supermarkets - are free of ice.
The Army helped deliver food to the elderly in Kent
The Highways Agency said motorways were mostly open, but a spokesman added: "We're warning drivers to check their route before setting off, and only to make essential journeys."
In addition to the UK's two main rock salt suppliers working at full capacity, a Cheshire chemical plant diverted 12,000 tonnes of salt destined for food and chlorine production in Germany to hard-pressed councils in the UK.
Ineos's initial supplies will go to councils in East Yorkshire, Pembrokeshire, Gloucestershire, Bradford, Sheffield and Fife.
The death of the man in Stockton brought the total of weather-related deaths during the cold snap to 27.
Parents pitched in to clear snow leading to their school
On Saturday, a 42-year woman died after being found near shops in Newcastle.
Easyjet and BA have cancelled some flights, and British Airways told passengers to go to their airport only after checking for delays and cancellations.
The Association of Train Operating Companies said most operators had returned to normal timetables - with 88% of scheduled trains running on time on Sunday - and many would run a fuller service on Monday.
Other disruptions blamed on the prolonged period of sub-zero weather include:
A&E departments treating more sprained and fractured wrists, ankles and collarbones
Red Cross volunteers having one of their busiest periods for 30 years
Soldiers delivering meals and supplies to vulnerable people in Kent
More call-outs for companies to fix boilers and frozen pipes
Many pubs and restaurants quiet as customers huddle at home
Airport and city centre hotels full of stranded passengers
Some panic buying of groceries in some shops
Some schools have taken unusual steps to stay open, from issuing parents and pupils with shovels, to Brighton College bringing in mattresses and sleeping bags for a pre-exam sleep-over.
At a village primary school in Wollaston, Northamptonshire, the head teacher asked parents to each bring a bucket of council rock salt with them on Monday to help replenish its stocks.
