Sardar Mehtab was elected to a provincial seat after winning the 1986 general election. He served as Provincial Minister for Law and Political Affairs from 1986 until 1988, when another general election was called.
Federal Minister for Kashmir Affairs and Northern Areas (1990–1993)
In 1990, Sardar Mehtab was elected to the National Assembly, for which he abandoned his provincial seat. He was subsequently appointed Federal Minister for Kashmir Affairs and Northern Areas. He held the post until 1993 when the General Assembly was dissolved and new elections were called.
Abbasi could not contest the general elections in 2002 for the National Assembly and had to settle for being a senator from March 2003 – March 2008.
As Senator (2003–2008)
Abbasi was among the few politicians who remained in Pakistan. He was an integral part of the party during the exile of Nawaz Sharif and was elected to the Senate of Pakistan in 2003 holding this office until the 2008 general elections.
Member of National Assembly (2008–2013)
In the 2008 general elections, Mehtab Ahmed Khan won the NA-17 Abbottabad seat. He also won the PF-45 provincial assembly seat and had to vacate both the Senate and the Provincial Assembly seats after the victory since a parliamentarian in Pakistan can only keep one seat. His son Shamoon Yar Khan won this seat. He was elected as the federal Minister for Railways on 31 March 2008 in the initial coalition between the PPP and PML after the elections. However, he, along with the other PML ministers, resigned less than two months later after differences regarding the restoration of the judges who were removed during the 2007 Pakistani state of emergency. In the 2013 general elections, Mehtab Ahmad Khan lost to his political rival for a seat in the national assembly.
The President of Pakistan, Mamnoon Hussain, on the advice of the Prime Minister, Nawaz Sharif, appointed Abbasi as Governor of Khyber Pakhtunkhwa. Abbasi took the oath of the office on 15 April 2014 in Peshawar. On 8 February 2016, Abbasi resigned as Governor of Khyber Pakhtunkhwa.
Head Of Aviation Affairs
After resigning as the Governor of Khyber Pakhtunkhwa and a year-long hiatus, Abbasi took up the role of aviation advisor to the prime minister on 14 February 2017. Abbasi took this position to improve the loss-making Pakistan International Airlines and turnaround its operations. In this short time, he has made big changes in the PIA, whereby the CEO and CCO were replaced. Furthermore, improvements have been made in aircraft surveillance to curb drug trafficking, which was rampant in the past. The New Islamabad Airport was also completed under his supervision.
