Milhazes is a Portuguese journalist living in Moscow. He disclosed here and here a document obtained by the Soviet Secret Service concerning talks held in Mars 1937 by the Polish Ambassador in Lisbon, Karl Dubic-Penter, with Premier Salazar. Main concern was the Spanish situation. Ambassor reported his feeling about Salazar's strong sympathy towards England.
Let's hope more documents will be released, mainly related with WW2 secret missions conducted by the Poles in Lisbon.
