The Pakistan Tehreek-e-Insaf (PTI) has appointed Sher Afzal Marwat as its senior vice-president, the party announced on Wednesday. Marwat is a former member of the National Assembly and a close aide to PTI chairman Imran Khan. He is a prominent figure in the party's Khyber Pakhtunkhwa province.

Marwat's appointment comes as the PTI faces a number of challenges, including a corruption investigation into Khan and the party's performance in the recent local government elections. The party is also gearing up for the 2023 general election.

In a statement, the PTI said that Marwat's "extensive experience and political acumen" would be invaluable to the party. "He is a proven leader and administrator who has a deep understanding of the party's ideology and objectives," the statement said.

Marwat thanked the PTI leadership for the appointment. "I am honored to have been appointed as senior vice-president of the PTI," he said. "I will work tirelessly to strengthen the party and to serve the people of Pakistan."

Marwat's appointment is likely to be seen as a sign of Khan's confidence in him. Marwat is a close ally of Khan and is seen as a loyal and competent leader. His appointment could help to unite the PTI's leadership and to boost the party's morale ahead of the 2023 general election.
