Sebastian Pinera, the winner of a weekend presidential runoff election in Chile, on Monday breakfasted with outgoing President Michelle Bachelet in a tradition meant to show the smoothness of political transition. The 40-minute meeting, in Pinera's mansion in the Chilean capital Santiago, was designed to show there was no bad blood between them, after a tightly fought campaign that pitted Pinera, a conservative, against Bachelet's leftwing candidate, Eduardo Frei. Pinera won the runoff Sunday, picking up 52 percent of ballots to Frei's 48 percent. Bachelet herself was constitutionally barred from seeking re-election. She is to hand over power to Pinera on March 11. During the run-up to Sunday's poll, Bachelet had thrown the full weight of her reputation and popularity behind Frei, managing to narrow the gap with Pinera though not by enough to guarantee victory. She also raised conflict-of-interest questions about Pinera's many investments, which include a television station and a 26-percent stake in Chile's flagship airline LAN. Pinera -- who lost his first presidential bid to Bachelet four years ago -- had complained that her 'interference' was not fair. He has promised to 'open the window and let in fresh air' after breaking the 20-year hold on power enjoyed by Bachelet's leftwing Concertacion coalition, ever since the end of the military dictatorship of General Augusto Pinochet. Pinera, whose fortune is estimated at 1.2 billion dollars, has promised to divest his LAN holding before taking office and has already set up a blind trust to manage most of his wealth at a distance. Late Sunday, he told 30,000 supporters that he would 'break down the walls dividing us and build new bridges to bring us together.' He was expected, however, to maintain a social welfare program established by Bachelet which has wide approval in the population, and which is partly credited with helping the prosperous nation cushion the blow of last year's global downturn.
