Zimbabwe’s main opposition party, The Citizens Coalition for Change, has said at least 80 of its supporters were arrested on Saturday while campaigning door to door ahead of crunch parliamentary by-elections next month and were being detained in the city of Masvingo, 300 kilometres south of the capital Harare. CCC’s president Nelson Chamisa last month told the AFP news agency that his party was under constant attack from the ruling party because it was poised to win the by-elections. The party also claims that the playing field is not level and that it is difficult to mobilise voters, complaining of strict gathering rules that include not being allowed to chant slogans, sing political songs or march in a procession.
