TRADE union leaders and MPs have condemned escalating US aggression against Cuba, calling on the British government to oppose further intervention in two open letters published today.

Union general secretaries including TUC’s Paul Nowak, Unison’s Andrea Egan, Unite’s Sharon Graham, NEU’s Daniel Kebede and PCS’s Fran Heathcote, slammed US President Donald Trump’s latest measures against the socialist-run island, including the indictment of its former president Raul Castro.

They described it as part of a broader campaign of “economic warfare, political aggression and destabilisation directed against the Cuban people,” warning the US’s actions risk “further inflaming tensions and creating a pretext for intervention against a sovereign nation.”

The statement was also backed by CWU general secretary Dave Ward, RMT’s Eddie Dempsey, UCU’s Jo Grady and GFTU’s Gawain Little alongside leaders from unions representing rail, firefighters, bakers and prison officers. 

It calls on the British government to oppose all attempts at foreign intervention and to demand an end to the US blockade and sanctions.

Cuba faces severe shortages of food, fuel and medicines following the Trump administration’s latest escalation of sanctions, which include cutting off oil supplies.

The other letter, signed by 36 MPs and peers from seven political parties through the all–party parliamentary group on Cuba, urged Foreign Secretary Yvette Cooper to publicly condemn what it describes as “falsified, inhumane and unprovoked” US attacks.

The parliamentarians warn Washington is attempting to move the US “closer towards a state of belligerence with the Republic of Cuba, on a clearly fabricated pretext.”

They argue that the indictment against Mr Castro must also be viewed in the context of a wider campaign of aggression, pointing to recent executive orders intensifying the blockade against Cuba, alongside increasingly provocative claims from US officials.

Cuba Solidarity Campaign director Rob Miller said the letters demonstrated “growing alarm at the increasingly dangerous direction of US policy towards Cuba.”

“At a time when the Cuban people are already enduring immense hardship caused by the US blockade and sanctions, the Trump administration is escalating tensions through threats, false accusations and economic warfare,” he said.

“The British government must not remain silent. Britain should stand firmly for peace, sovereignty and international law, and oppose any attempt to justify intervention against Cuba.”
