BRAZZAVILLE: Congolese opposition leader Paulin Makaya, recently released from prison after three years, has again been prevented from leaving Brazzaville, his family said Saturday. Border police stopped Makaya from boarding an Air France flight to Paris on Friday evening, his son Russel Makaya told AFP. From there, he had been due to fly on to London. “He turned up on Friday a little before 7:00 pm (1800 GMT) with his British passport. The border police turned him back immediately on the pretext that he is banned from leaving the country,” he said. Makaya was also stopped from travelling on September 28, officially because he did not have a permit to leave the country. But this time, his son said, he had the necessary papers — and a letter from the British embassy calling on the authorities in Congo to provide him with assistance to make the trip. A copy of this letter has been posted on social media, an AFP journalist noted.
