Speaking at Harry Mwaanga Nkumbula international airport upon her arrival from Lusaka, Mrs Wina said there is no reason to be suspicious of institutions of governance such as the ECZ.
She said it is worrying that politicians have gone into panic mode and are undermining institutions of governance.
ZANIS reports that the Vice President said the ECZ should be allowed to do its work without interference from external forces.
She said undermining the ECZ is equivalent to showing a vote of no confidence in the governance system of the country.
Mrs Wina also called for peace and unity in the country as the country heads for elections next Thurssday August 11, 2016.
She said without peace and unity, the country cannot survive.
Yesterday UPND members intercepted ECZ trucks in Livingstone on suspicion that they were carrying election materials.
The trucks were later cleared and drove to Lusaka under police escort.
