By Paul Nyathi|The Zimbabwe Electoral Commission has invited all the political parties registered under it and contesting the upcoming harmonised elections.

Sources within the opposition MDC Alliance told ZimEye.com that the electoral commission sent invitations to the political parties to send observers to see the printing of the ballot papers at Fidelity Printers in Harare on Friday morning.

The opposition MDC Alliance push hard through the courts demanding that ZEC introduces stringent security measures on the ballot papers to be used in the elections.

The demands came after the opposition parties indicated that the ruling party rigged the 2013 elections by feeding into the papers a specially designed paper which tempered with the vote.

There are over 120 registered political parties in the country.
