Polish prime minister says EU leaders will meet on Sunday and calls for greater defence mobilisation across Europe

Speaking alongside Costa, Polish prime minister Donald Tusk dropped a hint that there are plans for European leaders to meet in London this Sunday to discuss defence and security issues.

Here is what he said:

I hope that this greater [defence] mobilisation of Europe, of member states and Europe more broadly, will become a fact.

[Before meeting at the next European Council,] we will be in London on Sunday, together with our British friends and a group of leaders, to talk about these joint plans on defence.
