Slovakia's new prime minister Iveta Radicova, the first female head of government in the country's history, is set to make her first visit to European Union headquarters in Brussels on Tuesday, officials said Friday, according to dpa. Talks are likely to concentrate on Radicova's threat to refuse support for an EU bailout fund for Greece and renegotiate her country's contribution to a larger safety net, agreed by the bloc in May to keep other eurozone members out of financial trouble. "We will have an opportunity to see next week, when Mrs Radicova is paying a visit to the (European) Commission on Tuesday," Pia Ahrenkilde, spokeswoman to commission president Jose Manuel Barroso, told reporters in Brussels. Radicova's statements have rung alarm bells in EU circles, where they are seen as a potentially damaging crack in the eurozone's unity - something which would be unlikely to reassure markets still concerned by the euro's stability. During her visit, the Slovakian premier is also due to meet with the president of the council of EU member states Herman Van Rompuy, a spokesman told the German Press Agency dpa.
