Germany’s opposition Free Democrat party of Guido Westerwelle has said a centre-right coalition with Chancellor Angela Merkel is the only option ahead of next weeks federal election.Westerwelle rejected the possibility of a traffic light coalition with the SPD party and the Greens — seemingly the only combination that could deny Merkel a second term. The FDP are Merkel’s preferred choice to form a centre-right coalition but many believe they are too closely aligned, particularly on foreign policy. In Berlin the leader of Germany’s Green party Cem Özdemir said: ‘‘I would like to share this with you – Mr Westerwelle obviously wants to hire the removal men but he will have to cancel them for a 4th time because it wouldn’t be healthy to have somebody with his views, together with Mrs Merkel, being responsible for foreign policy – we must prevent this.’‘ The latest polls ahead of next Sunday’s vote put Merkel’s CDU on around 36 percent with there main left of centre rivals the Social Democrats attracting about a quarter of the electorate. The Greens have risen to record highs on 12 percent, just behind the business friendly Free Democrats of Westerwelle. Oskar Lafontaine’s Die Linke also appears to hold around a tenth of the potential poll and yesterday Chancellor Merkel accused her SPD rival Frank-Walter Steinmeier of considering an alliance with the radical left-wing party.
