Worked on Gib a few times,gibraltarians are staunch pro-uk,they don't want to be called Spanish,they actually view it as an insult, but they were pro-europeans,i think it was 98% wanted to remain because 4000+ Spanish cross from la linea every morning to work on the rock, theres a statue on the Spanish side dedicated to the spaniard gib workers, if Spain wants the rock back perhaps first they should hand Ceuta back to the moroccans?Just as a token good faith gesture
