Jacaranda FM has reported that on June 14, the leaders of the main opposition Citizens Coalition for Change (CCC), Job Sikhala and Godfrey Sithole, were detained.

They each had to pay 50,000 Zimbabwean dollars ($78) for bail.

Their release came just days after a Commonwealth mission arrived to determine whether the situation was favourable enough to justify Zimbabwe's reinstatement into the association of primarily former British colonies.

"14 of our members were granted bail, which has given us relief," according to party spokeswoman Fadzai Mahere, who spoke to AFP.

However, she noted, "we deplore the continuous abuse of state institutions by Zanu-PF (the ruling party), including the police force, the jail service, and the court system to stifle political opponents.

Sithole was released last week, but his firebrand lawyer Sikhala is still being held at a high-security facility outside of Harare.

Sikhala has a political career spanning more than 20 years and has been detained 67 times without ever being found guilty.

Mahere claimed that there has been an increase in violence, persecution, and arbitrary arrests of our members for baseless reasons.

The nation will hold national elections the following year.

After Zimbabwe's membership in the Commonwealth had been suspended due to the country's violent and corrupted elections the year before, ex-strongman Robert Mugabe furiously withdrew his country from the organisation.
