Cambodia’s election panel on Friday began a campaign to get voters to turn out for a July 29 general election, despite the concerns of some Western nations and the United Nations that the vote might not be free or fair after a key opposition party ban.  The campaign will feature television programs to increase awareness about voting rights and the identity documents voters need to take to polling stations, he added. The campaign comes amid repeated calls from former opposition leader Sam Rainsy for Cambodians to boycott the election if his dissolved Cambodian National Rescue Party (CNRP) is not allowed to take part. The CNRP was dissolved last November after its leaders were charged with treason for allegedly plotting to overthrow Hun Sen’s government with the help of the United States.
