LABOUR is complaining to the Ministry of Defence (MoD) after the Royal Navy endorsed anti-Corbyn content on social media.

The move comes as an official navy Twitter account “liked” a tweet by ITV breakfast anchor Piers Morgan.

In the tweet, Mr Morgan criticised Labour leader Jeremy Corbyn for planning to boycott Donald Trump’s state visit dinner in June.

Lib Dem leader Sir Vince Cable and Commons speaker John Bercow have also said they will not support the US President’s trip to Britain.

But on Friday Mr Morgan focused his anger on Labour, tweeting: “Hi @jeremycorbyn — why would you proudly boast about dining with the leader of Hamas, a terrorist group, but refuse to dine with the President of the United States, our most important ally? Genuinely curious.”

The tweet was subsequently liked by the official Twitter account for Her Majesty’s Naval Base Devonport, Britain’s largest navy base.

A Labour Party spokesman told the Morning Star: “This is unacceptable and we are contacting them with our complaint.”

The armed forces are notionally politically neutral and are not allowed to support any domestic political parties.

An Afghan war veteran called for an independent investigation, warning that this was not an isolated incident.

Veteran and author Joe Glenton told the Morning Star: “This follows on from threats of a coup by a serving general, images of paratroopers shooting a picture of Corbyn and increasing evidence of far-right activity among serving personnel.

“There needs to be a thorough investigation into the scale of this issue by a body completely independent of the military.”

The tweet has now been “un-liked” and a Royal Navy spokesperson told the Star: “The Armed forces are apolitical organisations and this was human error.”
