* Britain hit by biggest snowfall in 18 years
* Anger as London bus service is totally cancelled
* One in five workers take the day off
* Brothers found dead on Mount Snowdon
* Thousands of schools closed due to treacherous roads
* Huge tailbacks despite warning drivers should stay home
Britain's worst snowfall for 18 years is set to last all week - and could cost the country's economy up to £3 billion.
Around one in five workers stayed at home today, according to a poll, and many are likely to fail to show up for work tomorrow.
Those who did make it into work this morning faced a battle to get home tonight after the Arctic weather caused widespread chaos.
Roads were blocked, airports closed, train services stopped and almost 3,000 schools closed due to the massive snowfall.
With roads blocked, much of London's bus service still out of action and many underground lines suspended, it is feared some in the capital may end up stranded.
Business chiefs estimated the cost of the bad weather to the economy would be £1.2billion but that it could rise to £3billion by the end of the week.
