British Prime Minister Boris Johnson on Tuesday left for a tour of Poland and Estonia, Britain’s European allies neighbouring Ukraine which is fighting a bloody conflict with Russia. In Poland, Johnson has a meeting with Prime Minister Mateusz Morawiecki to “underpin” the UK’s financial and diplomatic support for central Europe as it faces the prospect of a humanitarian crisis. He then travels on to Estonia, where he will join NATO Secretary General Jens Stoltenberg to meet British troops on the frontline of the Russian invasion in Tapa. “Today I will visit Poland and Estonia, two countries that are acutely affected by the current crisis in Ukraine. We have shared values that are more important than ever to protect, as the humanitarian situation gets worse,” the UK PM said. “Alongside all our international allies the UK will continue to bring maximum pressure to bear on (Russian President Vladimir) Putin’s regime to ensure he feels the consequences of his actions in Ukraine. We speak with one voice when we say, Putin must fail,” he said.
