"we can, have and will survive debt ratios vastly higher than we have now. There is no need to panic. Such things are normal, especially during and after a crisis, and we do recover." https://www.taxresearch.org.uk
"Government debt is not then a matter of concern right now, unless the fact that big savers have confidence in the government to be the best person to look after their money is an indication of a lack of confidence in it. And I promise you, that has never been the case to date." https://www.taxresearch.org.uk
"In cash terms, we have the highest government debt we have ever had. But the cost is exceptionally low, and even if we increase what is described as borrowing as a consequence of coronavirus the impact will still be very small given current, exceptionally low interest rates, which look like they will persist for a very long time.
Please do always recall, that every penny the government spends on interest becomes someone's income - and most of it in the UK. And there is good reason for that: UK national debt is just a savings mechanism. There is nothing more menacing or threatening about it to our wellbeing than the amount saved in banks and building societies." https://www.taxresearch.org.uk
