Campaigning has ended ahead of presidential polls in Portugal tomorrow. Centre-right candidate Anibal Cavaco Silva is widely tipped as the favourite to win, which would be a set back for parliament’s divided Socialists.A win by Silva, who is a former prime minister, would give Portugal its first elected right of centre president since a 1974 revolution that installed democracy. Most of the opinion polls put Socialist Manuel Alegre, the deputy speaker of parliament, in second place. Mario Soares, who has been president twice, and was a founder of Portugal’s democracy, trails with three other leftist candidates. The 81-year-old is supported by Prime Minister Jose Socrates. Also in the running to replace president Jorge Sampaio is the leader of the Portuguese Communist Party Jeronimo de Sousa.
