The UK government is elected to look after UK citizens. Other countries have their own politicians who should look after their own countries and who are equally capable of borrowing money. Additionally it may help to stem the cycle of smashing countries up with high explosives by bombs and missiles etc and then repairing all the damage via overseas aid. Money will also be saved in not needing politicians and civil servants to visit other countries in connection with aid programs.
Repeal all laws that allow taxpayers money to be spent on overseas aid. At present politicians borrow money then give it to people overseas so getting our country into greater debt forcing citizens here to pay more in tax with reduced facilities.
