Zimbabwe police arrested an opposition MDC lawmaker in parliament on Monday and more arrests of MPs are feared, a party spokesman said.
Zimbabwe's opposition MDC said on Monday President Robert Mugabe's appointments of lawmakers were a unilateral decision which threatened power-sharing talks.
"They have arrested one of our MPs, here in the chamber. We hear that they are also looking for a total of 15 of our members of parliament as part of an evil ploy to rig the elections for parliamentary speaker," MDC spokesman Nelson Chamisa said.
"Clearly they have chosen the path of arrogance, unilaterilism, that's a serious blow to confidence building in the talks," MDC spokesman Nelson Chamisa said.
Zimbabwe's parliament is due to elect a speaker later on Monday but Chamisa said the MDC will not allow the vote to go ahead over the arrest of the opposition MP.
