PRIME Minister Matti Vanhanen rejected allegations on 29 September in a Finnish news documentary that he received building materials free of charge from a construction company, Deutsche Presse Agentur (dpa) reported from Helsinki. During a brief news conference, Vanhanen rejected thea report on Monday evening by public broadcaster YLE and said that he had paid for the materials - lumber for bookshelves sas for his house built 13 years ago. Who would think I would risk my political career and credibility for a pile of lumber? Vanhanen asked, adding that YLE should present evidence to back up the allegations. Public broadcaster YLE’s investigative programme Eye Witness on alleged that the material was delivered by a construction company during the 1990s when Vanhanen was building a house. The National Bureau of Investigation is set to investigate the claims. The YLE documentary, citing anonymous sources, suggested that the construction firm hoped to secure contracts from a youth housing foundation of which Vanhanen was chairman. The youth housing foundation has also donated money to Vanhanen’s Centre Party and his 2006 presidential election campaign, YLE reported. The programme was broadcast amid an ongoing row over election-campaign financing that has embroiled leading politicians and parties, and even triggered calls for Vanhanen to step down. Parliament was to debate reforms in election funding on 29 September.
