WARSAW – The governments of Poland and Hungary threatened Monday to veto the European Union's next seven-year budget and coronavirus recovery plan due to a new mechanism that would link funding to the rule of law.The 27-nation bloc's 1.8 trillion euro ($2.1 trillion) budget for 2021-2027 was agreed upon last week after months of tough negotiations, and is meant to take effect within weeks.It has sparked stiff resistance in Warsaw and Budapest, where right-wing governments are adamantly opposed to a tool that could cause them to lose EU money if they continue with policies seen as eroding democratic standards.Hungarian Prime Minister Viktor Orban’s press chief Bertalan Havasi said Monday that Orban had written a letter to German Chancellor.
