Foreign Secretary William Hague has reiterated his support for Ukraine's presidential election, saying Ukrainians "cannot be bullied" out of holding the poll on 25 May.
"We do have to support Ukrainians making their democratic choice," Mr Hague told the BBC's Today programme. "The people of Ukraine deserve to be able to make that choice."
Mr Hague also defended the UK's interventions to prevent the Ukrainian conflict from worsening, which have included imposing sanctions on Russia and Russians with links to President Vladimir Putin.
"This is absolutely part of Europe and European civilisation," he said. "Our national interest lies... in Ukraine being a stable democracy."
European Union foreign ministers added 13 people to their visa ban and asset freeze list over Ukraine's crisis.
Well that’s the voting over, and no surprises so far. A ‘Yes’ vote claimed to be 89% in Donetsk, and suddenly Ukraine is no more.
Nearly 90 percent of voters in eastern Ukrainian region voted for self-rule, the head of the separatist election commission said.
