MORE than 100 MPs have voiced “grave concern” over Donald Trump’s Cuba oil blockade, calling on PM Sir Keir Starmer to oppose the US president’s “collective punishment” of its civilian population.

Ministers were urged to reject Washington’s threat to slap tariffs on any other country that ships fuel to the island after it kidnapped Venezuelan leader Nicolas Maduro in January.

The US has blocked Venezuelan oil supplies to Cuba’s socialist government, which said last week that it had not received any ​fuel in three months. 

Your Party leader Jeremy Corbyn, Labour, SNP, Plaid Cymru, Green, SDLP, and Lib Dem MPs have now signed an early day motion by Labour MP for Montgomeryshire and Glyndwr Steve Witherden.

Mr Corbyn told the Morning Star: “The aim of the criminal and inhumane blockade by the US is clear: to starve the Cuban people into submission. They will not succeed.

“As much as the United States would wish otherwise, Cuba is not alone.”

They collectively called on the government to reject the “unjustifiable” sanctions and US claims that Cuba poses an “extraordinary” threat.

A Stop the War Coalition-Venezuela Solidarity Campaign protest will oppose the prosecution of Mr Maduro outside the US embassy in London at 5.30pm tomorrow.

Mr Witherden, who is chair of the all-party parliamentary group on Cuba, said: “We tabled the motion to oppose Trump’s illegal aggression against Cuba. 

“It is outrageous to starve a whole population to try to force your will on another sovereign country.” 

His EDM calls on Parliament to note that “such measures amount to the collective punishment of a civilian population and will inevitably lead to avoidable deaths.

“Cuba is already facing a severe energy crisis as a result of the long standing US blockade, and… any further restrictions on fuel supplies will have a severe impact on healthcare, food production, transport, education, essential public services and access to electricity, fuel, and medical infrastructure,” it adds.

Mr Trump’s threats undermine and breach other countries’ national sovereignty and international law, MPs said.

They backed the calls for the government “to oppose this executive order, reject all extraterritorial sanctions, uphold the right of sovereign states to determine their own trading relationships with Cuba, and advocate for the rescission of measures that endanger humanitarian wellbeing.”

Socialist MP Richard Burgon, who was in Cuba this weekend delivering humanitarian aid with an international delegation, said: “In Cuba I saw the cruel consequences of Trump’s total ban on fuel entering the country, including its impact on the ability to provide healthcare to those in need. 

“Cutting off fuel to an entire country is an inhumane attempt by Trump to strangle the Cuban people into submission. It is illegal and it’s putting lives at risk.

“The UK rightly votes against the US blockade at the UN each year, but that must now be matched with action. It should follow Spain’s example and provide emergency humanitarian aid.”

Green Party parliamentary leader Dr Ellie Chowns said: “Trump has intensified his threats against Cuba following the collapse of the island nation’s energy grid under a US-imposed oil blockade, declaring just yesterday that he believes he will ‘take’ the country and ‘could do anything [he] want[s] with it. This cannot continue.”

Cuba Solidarity Campaign director Rob Miller said his group is delighted with the number of MPs who have signed the motion, saying: “Together they represent over seven million UK constituents. 

“We now hope the UK government will move quickly to send humanitarian support to Cuba, a country with which we have had full diplomatic and friendly relations for over 120 years.”

While early day motions are not binding, they are part of formal parliamentary procedure and can send a clear message to the government bringing forward areas of concern for MPs from across the House.

Today it emerged that US suppliers have shipped approximately 30,000 barrels of fuel to Cuba’s private sector this year to date.

Documents and shipping data viewed by Reuters suggest a Trump administration plan to give private business a leg up over state-run enterprise is well ​underway.

Stop the War Coalition national convener Lindsey German said: “Trump’s siege of Cuba is completely horrific. 

“It’s not just the usual US imperialism but a new gangster imperialism which has seen the bombing of Venezuela, the kidnap of its President Nicolas Maduro and the grabbing of the country’s oil — making sure Cuba doesn’t get any of it in the process. 

“This is why the protest at the US embassy in London, organised by Venezuela Solidarity Campaign and supported by Stop the War is so important in bringing together campaigners, trade unionists and legal experts to stand up for sovereignty and international law.”
