PRAGUE (Reuters) - A junior party in the Czech center-right coalition called on its ministers to quit the government on January 10 after a row with Prime Minister Petr Necas, threatening the cabinet's survival, the LIDEM party's chief Karolina Peake said on Thursday.

The new crisis in the government comes after Necas fired Peake as defense minister earlier on Thursday, just a week after she took office.
