The Greek government will ask for parliament's approval on Friday to negotiate on the text of "prior actions" that could form the basis of a cash-for-reforms deal with the country's international creditors, a government source said. As Greece races to stave off bankruptcy, its creditors want Athens to pass laws on reforms as "prior actions" to convince the international lenders of the government's intent. There will be one vote on whether to authorise the government to use the text as a basis for talks, the source said.
