The Romanian president has approved the Prime Minister’s sacking of Interior Minister Dan Nica, deepening a standoff that could bring down the government.Prime Minister Emil Boc proposed a replacement for Nica from his own party, the Democrat Liberals sending the centre-left coalition into crisis. The coalition’s Social Democrats (PSD) have threatened to leave the cabinet. Boc’s Democrat-Liberals and their leftist partners have ruled since they took power in December, sparring cost-cutting reforms and trading blame for economic woes. The current clash is seen as a tactical manoeuvre ahead of the November presidential election. A break-up of the coalition would put in question Romania’s ability to meet International Monetary Fund conditions – aid vital to combating a painful recession.
