Ijaz entered politics following his father's death. His father was re-elected as an MNA of the
Pakistan Muslim League (N) (PML-N) from NA-79 in the preceding
1997 general election, but died while in office. Ijaz left his party after the poll and began to tilt towards the PML-N. In 2010, Mudassar Qayyum Nahra's membership was suspended and his seat in NA-100 fell vacant after Ijaz filed a petition in an election tribunal of the
Lahore High Court, seeking Nahra's disqualification over a
fake degree case. In the petition, Ijaz invoked Articles 62 and 63 of the
Constitution and argued that Nahra was ineligible to hold public office. Ijaz did not contest in the by-election that followed; the seat was won by
Chaudry Tussadiq Masud Khan, a
PPP candidate who defeated Mudassar's brother and also the PML-N's designated candidate,
Azhar Qayyum Nahra. In the lead-up to the
2013 general election, Ijaz was tipped as a strong candidate in NA-100 alongside his main political opponents, Azhar Qayyum Nahra of the PML-N and Chaudry Tussadiq Masud Khan of the PPP. Nahra enjoyed the support of his
Jatt community, while Ijaz was backed by the Rajput community. In November 2014, Ijaz joined the opposition party
Pakistan Tehreek-e-Insaf (PTI) and served as a senior core member of the party. In the
2018 general election, he was fielded as the PTI's candidate for his newly delimited electorate of
NA-84. Although the PTI won the election and was able to form both the federal and Punjab provincial governments, Ijaz was unsuccessful in his constituency. He received 89,943 votes and lost to the PML-N's Azhar Qayyum Nahra by a margin of around 30,000 votes (for the third time consecutively). The result was noted to be consistent with the PML-N's overall electoral dominance in Gujranwala District. In the 2024 general election, he won a seat in the National Assembly. On 29 February, he was sworn in as a Member of the National Assembly. However, following a vote recount, his opponent was declared the winner. This notification, was cancelled by LHC later on though. In August 2024,Supreme Court of Pakistan nullified orders of Lahore High Court and disqualified him again. ==Political appointments==
