David Cameron discussed the situation in Ukraine with Chancellor Merkel and President Hollande.
Following the calls, a Downing Street spokesperson said:
The Prime Minister spoke separately to both Chancellor Merkel and President Hollande this evening to discuss the situation in Ukraine.
In both calls, the leaders agreed that the international community should speak with one voice and send a clear message to Russia that its actions in Ukraine were completely unacceptable. They agreed they must continue to work very closely together in response to events in Ukraine including in preparation for the special European Council which has been called on Thursday. It would be important to be clear about the costs and consequences for the Russian government of continuing to violate Ukraine’s sovereignty; and of supporting the people and government of Ukraine in support of their efforts to build an inclusive government and tackle economic challenges.
They agreed there could be an important role for the United Nations, and potentially other international organisations, in facilitating the dialogue between the Russian and Ukrainian authorities which is central to the shared objective of de-escalating tensions in the region.
