However, the Election Commission said re-polling would only be held at 43 stations where voting was stopped by it following complaints of rigging and late opening of stations during the May 11 general elections.
The Commission had held a meeting with leaders of the MQM, Pakistan Tehreek-e-Insaaf and Sindh government officials earlier in the day.
MQM leader Farooq Sattar told the media they had demanded re-polling at all polling stations of the NA-250 constituency here and not just the 43 selected polling stations.
"Ballot boxes did not reach on time and in some cases, they never reached at all," he said adding it would be unfair to deny the same right to re-poll to all the voters in the constituency.

Pakistan Tehreek-e-Insaaf leader Arif Alvi told the media that they wanted re-polling across Karachi not just in NA-250.
According to him, polling conducted in the city of Karachi was not free and fair and referred to video evidence of rigging aired on different television channels.
The NA-250 constituency has become major flash point between the MQM and Pakistan Tehreek-e-Insaaf where the latter is said to have a very good chance of displacing the MQM.
