The PM’s spokesperson did not contest the Times report claiming that, if the UN security council votes on a resolution criticising the US intervention in Venezuela, the UK will abstain. (See 12.11pm.) The spokesperson confirmed that Yvette Cooper, the foreign secretary, will make a statement to MPs this afternoon about Venezuela and he suggested she would cover this point in her statement.

The spokesperson claimed it was “hypothetical” to suggest, as Emily Thornberry did in her Westminter Hour interview, that the US move would encourage China or Russia to topple leaders that they don’t like. Asked if Thornberry had a point, the spokesperson said:

"I don’t think it’s massively helpful to get into hypothetical scenarios or make comparisons. We respect international law, and we expect countries to do the same."

The spokesperson also declined to comment on Trump’s suggestions that he might seek to topple the regimes in power in Cuba or in Colombia. Asked about these countries, the spokesperson said these were “hypotheticial scenarios”. When it was pointed out that Trump’s threats to these countries go beyond the hypothetical, the spokesperson replied:

"The UK’s position on this is clear. We respect international law and any soveriegn state that recognises international law must set out the legal basis for its decisions and actions. That is for the US to speak to."
