David Cameron has urged voters in the coming election not to pass on a legacy of debt to their children. He must be joking!

Tory and Liberal party debts have been passed down by grandfather after grandfather from 1720, the South Sea bubble to the same two party’s coalition, doubling the National Debt in 2015.

Add on the Napoleonic Wars (1800-15), Crimea (1853-6) Boer War (1899-1902), WWI (1914-18), WWII (1939-45) and many more in America, Canada, Europe and India. Nothing to do with the Labour Party, they got their first majority government in 1945 after WWII.

National debt as a percentage of GDP was 250 per cent, equal to nearly three years of national income. To pay these old debts, the government of the day sold consolidated annuities, securities without redemption with a fixed annual interest; we are still paying interest on those debts because a lot of the original debt has never been paid.

In 2010 the National Debt was £700bn. In the 290 years from 1720 to 2010 we had 260 years of Tory and Liberal government and 30 years of Labour government.

From 2010 when the National Debt was £700bn to now, with a coalition government of Tory and Liberal parties, the National Debt has doubled, and the same old debtors.

Can we continue with these old and prolific spending parties? The Tories want to take us back to the 1930s; give them another five years and it will be the Victorian era they miss. They can’t compete with the 21st century and to think people still persist with the myth they are better with the economy. Nuts is all one can call them.
