BELGIAN Prime Minister Jean-Luc Dehaene will arrive 24 hours later than he was expected in South Africa — meaning he will miss a concert of Belgian singer Helmut Lotti in Johannesburg on Sunday. Dehaene was unable to leave Brussels on Saturday evening as scheduled because of a technical problem with the military plane on which he was flying. The first Belgian prime minister to visit South Africa, Dehaene will leave on Sunday evening and fly directly to Cape Town, where the official part of his week-long visit will start.
