Mate, calm down. Even something as simple as searching for 'uk debt' on google brings up this little snippet;
Since 2008, National Debt has increased sharply because of:
'Economics recession (lower tax receipts, higher spending on unemployment benefits) The recession particularly hit stamp duty (falling house prices) income tax and lower corporation tax.
These cyclical factors have exposed an underlying structural deficit
Financial bailout of Northern Rock, RBS, Lloyds and other banks.'

Here's another one;
'In the 20 year period from 1986/87 to 2006/07 government spending in the United Kingdom averaged around 40 per cent of GDP.[14] As a result of the 2007–2010 financial crisis and the late-2000s global recession government spending increased to a historically high level of 48 per cent of GDP in 2009–10, partly as a result of the cost of a series of bank bailouts.'

And as for slashing welfare and cutting government spending, it has just as much chance of sending the UK deeper into debt as it does of solving the problem. Slashing government spending at the level you advocate would undoubtedly reduce economic growth, which would in turn drastically cut tax revenues, which would leave the government with a shortfall in revenue versus savings gains from the cuts.
As a nation, the UK's always maintained that an average 40 percent debt to GDP ratio was the maximum sustainable amount of debt. The only thing that drove it over the edge, into the fifties and sixties, and then on from there, was the financial crisis, caused by ding ding ding! The bankers. How? Because tax revenues fell, and economic growth slumped, meaning the government had to pump money into the economy to keep it afloat, which meant borrowing the money, seeing as tax revenues had slumped. However, the extent of the crisis meant that QE, and government spending on alleviating the effects, continues to this day, and with decreased revenues, the only place that money is going to come from is from borrowing. Cutting services has the potential to send the country spiralling further into debt (

I repeat, the banks caused this.
