A key Egyptian negotiator with the International Monetary Fund said yesterday he has resigned as first deputy finance minister, in a potential blow to Cairo’s prospects of an early IMF deal. Hany Kadry Dimian has been the crucial point man in Egypt’s protracted and so far fruitless negotiations to obtain a $4.8bn (£3.09bn) loan needed to help combat a severe economic crisis. He said his next move is “not decided”. A senior technocrat appointed in 2007, Kadry survived five finance ministers in office since the 2011 uprising that overthrew former autocratic President Hosni Mubarak. He gave no explanation for his decision to quit.
