EU leaders hope to face down the Hungarian leader Viktor Orbán and keep their promise to find another €50bn (£43bn) for Ukraine despite his threat to veto extra funds during a crunch summit.
“There is no [one] plan B, there are plan Bs and if need be, we can go to Z,” said one diplomat, expressing the determination of the EU to ensure Orbán’s threats are not a barrier to Ukraine securing much-needed financial and military assistance to fight Russian invasion forces.
