LISBON: Portugal’s President Marcelo Rebelo de Sousa on Tuesday (Wednesday in Manila) acknowledged his country’s not always positive colonial past, during a visit to the former colony of Guinea-Bissau. Making the first visit to the country by a Portuguese head of state for 31 years, Rebelo de Sousa said Portugal “fully acknowledges” its colonial past “including those aspects, which were not positive.” The West African nation of Guinea-Bissau fought a war of independence and became a sovereign state in 1974.
