PRAGUE (Reuters) - New Czech Prime Minister Josef Tošovský pledged on Friday that his government would boost economic reform and privatisation and step up efforts to fight crime and corruption. President Václav Havel formally appointed Tosovsky's 16 ministers, who were named on Wednesday, at a brief ceremony in Prague Castle. "Premier Tošovský succeeded in forming a government which has a chance to bring to our politics new spirit, new dynamics...and renew the confidence of citizens in a democratic system and politics," Havel said. Tošovský, a former central bank governor appointed after the government of Václav Klaus collapsed over a party financing scandal, said he would present its programme to parliament within 30 days. He said it would continue negotiations on Czech membership of NATO and the European Union. The government would "renew the pace of economic reform, including privatisation, and create the preconditions for the future growth of our economy". He pledged to act resolutely against crime and corruption and "renew the faith of citizens in the law" and said the government would strive to be more transparent in its work. Tošovský's cabinet is likely to be short-lived ahead of early elections. He has said its mandate will not extend beyond 1998 and the main opposition Social Democrats have made their support for it conditional elections being held in June. The daily Mlada Fronta Dnes reported on Friday that Havel would hold a meeting in mid-January with the three members of the centre-right coalition which formed the old government and the Social Democrats to fix a date for new polls. The new government is drawn from the old coalition but includes several non-party ministers. Some analysts have said the presence in the new lineup of prominent members of a rebel faction within Klaus's Civic Democratic Party (ODS), including Finance Minister Ivan Pilip, could split the party's parliamentary deputies and make it difficult for the government to win a confidence vote. The pro-Klaus leadership of ODS said later at a news conference that the rebel ministers were not recognised as representing the party. Klaus himself is on holiday. The outgoing coalition held 100 of the 200 seats in parliament, so a split in the ODS would make the support of other parties vital. The Czech Republic has long been considered in the vanguard of economic reform in Eastern Europe but its image was tarnished last year as the weakened government struggled to cope with a severe economic downturn. The crown has strengthened since Tošovský's appointment and has held steady since his cabinet was announced. It was unchanged at around 19.38 to the mark on Friday.
