The Election commission of Pakistan (ECP) on Monday announced that re-election in Shangla's constituency of PK-23 will be held on September 10.

The results of polls in the Khyber Pakhtunkhwa Assembly constituency, where Pakistan Tehreek-i-Insaf's (PTI) Shaukat Yousafzai had emerged as the winner, were declared void due to low turnout of female voters.

The Elections Act, 2017 requires the ECP to declare an election null and void if women’s turnout in a constituency is less than 10 per cent of its total polled votes.

Yousafzai had earlier termed the ECP verdict "cruel", saying that the commission should have ordered the re-polling of female voters only instead of declaring the whole election void.

"It is not easy to hold elections in Shangla," he claimed. "We will suffer due to the re-election in the constituency."

The notification issued by the ECP states that the candidates who contested the July 25 elections will be able to compete the September 10 re-poll under the same party symbols.
