The EU will be complicit in violence if it stays silent over state "brutality" in Catalonia, an SNP MSP has said.

Sandra White, MSP for Glasgow Kelvin, called on the EU to speak out over the hundreds of citizens injured in clashes at polling stations during the October 1 independence referendum.

A motion calling on the UN, EU and Council of Europe to act to mediate negotiations to reach an agreed solution between the Spanish government and Catalan pro-independence leaders was passed by acclaim at the SNP conference in Glasgow.

Delegates heard from SNP politicians who travelled to Catalonia to observe the disputed referendum which was won by the Yes side.

White said: "The brutality in Catalonia I have never seen the like of and I hope never to see that like again.

"I absolutely implore the EU, Europe - you cannot stay silent on this. If you stay silent you're complicit in the attacks that were put upon the Spanish people."

Douglas Chapman MP said the EU's response to the violence had been "very, very disappointing for may of us in this room who are very pro European Commission and pro European Parliament".

"It left a very nasty taste indeed," he said.

"I can't imagine any situation where 800 people were injured at a football match or a pop concert - injured by the state - and nothing was said about it. Again it doesn't bode well for the future.

"This motion is about the right of citizens to self determination, it's about how people voted in the face of violence and intimidation by the state, it's about the international community and how we must mediate this through a negotiated and peaceful future between Madrid and the Barcelona government."

Joanna Cherry MP added: "What I saw was repression on a scale I never expected to to see in a Western European democracy.

"Let's call for international mediation to resolve this situation and a recognition of the Catalonia people's right to choose democratically and lawfully their future."
