I have an idea that may help get the debt under control, I will share it with all the world leaders I know of and let them decide if it would be any use.
What I would do is open a patriot Raffle lottery.
The prizes of the lottery would be fixed.
First prize is £12 million
Second prize is ½ @ £6 million.
Third prize is ⅓ @ £4 million.
Fourth prize is ¼ @ £3 Millon
Fifth prize is ⅙ @ £2 million
The rest of the money is used to pay off government debt. The lottery wouldn't need to pay off the debt but just stop it from growing bigger and pay the interest. The second goal would be to try and reduce the debt a bit but inflation would make the debt smaller anyway. I would say work out how much is needed to stop it growing bigger every month and go from there and adjust the frequency of the lottery to hit that first goal.
What ever choice the leaders make, I wish them good luck and peace.
