The federal government has installed an electronic voting machine (EVM) at the Parliament House in a bid to observe its accuracy and efficiency for usage in the upcoming general elections. A display centre of the EVM has been set up at the Gate No 1 of the Parliament House and a technical officer is also deputed there to guide parliamentarians and media persons, a private TV channel reported. The Ministry of Science and Technology installed the machine on the instructions of Prime Minister Imran Khan to avoid delay in the election results.
