"For a long time, Karachi’s NA-250 has been one of the city’s most unpredictable constituencies. It still is," writes Nadeem F. Paracha in his Sunday column in Eos. "Now even more so, as due to last year’s delimitation of constituencies, it has been merged with NA-249 to become NA-247."

"One of the biggest constituencies of Karachi has become even larger

"As NA-250, it constituted the city’s main 'posh' localities as well as some thickly-populated middle- and working-class areas. All of these localities are dotted by hefty pockets of Mohajir, Pakhtun, Baloch, Punjabi and Sindhi populations. The ethnic and class diversity of this constituency has become even more widespread with the merger of NA-249."
