HARARE, June 5 (Xinhua) -- More observers are arriving in Zimbabwe for pre-election assessments with a joint delegation from the International Republican Institute (IRI) and the National Democratic Institute (NDI), which is on a seven-day mission, starting its mission on June 2.

Zimbabwe holds harmonized presidential, parliamentary and local government elections on July 30 and so far a number of regional and international teams have sent pre-election observation teams to assess the situation in the country.

Among these are the European Union, the Commonwealth, the Southern African Development Community and the Common Market for Eastern and Southern Africa.

IRI, whose headquarters are in Washington DC, says it is a non-profit, non-partisan organization dedicated to advancing freedom and democracy worldwide.

NDI, which is also domiciled in the U.S., says it is also a non-profit, non-partisan organization working to support and strengthen democratic institutions worldwide through citizen participation, openness and accountability in government.

A statement from the delegation on Tuesday said that the mission was responding to the public welcome of international observers by Zimbabwean President Emmerson Mnangagwa and requests from political leaders and civil society organizations.

The delegation will meet with government officials, political party leaders, election authorities, and representatives of civil society and the international community before presenting its mission findings at a press conference on Friday.
