UNION bosses have expressed their disgust at an act of vandalism on a Glasgow memorial. 

The tribute to the Blockade Runners to Spain, which is situated next to the River Clyde, was only erected months ago but has come under attack by vandals in the city. 

The tribute is dedicated to the seafarers who broke Franco’s blockade of Republican ports.

Thirty-five merchant navy and eight Royal Navy seafarers died and scores were injured on vessels attacked by submarine, naval and aerial forces under fascist control between 1936-38. 

The memorial is on the Clyde walkway next to the Jamaica Street bridge

Posting on Twitter, the RMT's Glasgow Shipping branch posted a photograph of the desecrated memorial.

Branch chairperson Dan Henderson added: "It makes me so sad to to see that someone could do this, so much work went into the memorial from so many dedicated people. 

"We would hope that the reaction of Glaswegians and the media will help to educate people on the selfless sacrifices that the Blockade Runners made to help those less fortunate than themselves."
