An FCO spokesperson said:
The United Kingdom condemns the steps taken by the Maduro regime to forcibly block and frustrate the democratic process of the Venezuelan National Assembly on 5th January.
Their attempts to prevent the re-election of Juan Guaidó ignore the interests of both the country and its people, undermine respect for democratic institutions and principles, and the rule of law. The Assembly must be allowed to operate legally and to fulfil its responsibilities without fear or impediment.
The United Kingdom underlines its support for interim constitutional President Guaidó and his efforts to lead Venezuela towards a peaceful and democratic resolution of the appalling crisis the country is facing.
