Presidential spokesman Dmitry Peskov said his presence had been confirmed, and Russia was preparing for his visit. However, Mr Peskov did not mention Kim Jong-un by name, sparking speculation that another official may attend. Kim Jong-un has not made any overseas visits since taking power in North Korea in late 2011. South Korea’s Unification Ministry told Yonhap that the reference to the leader could be ambiguous, as Kim Yong-nam is the nominal head of state.  Earlier this month, reports emerged suggesting Russia could be the site of Mr Kim’s first official visit. Foreign Minister Sergei Lavrov told journalists on 21 January that Russia had invited Mr Kim to the 9 May celebrations to mark the 70th anniversary of the end of WW2. He said that the “first signal was positive” from the North Korean government. More
