Afghanistan's Parliament rejected President Ashraf Ghani's nominee Mohammad Masoom Stanekzai for defence ministry on Saturday, a crucial post that has been vacant for months as stretched security forces fight to secure territory from a revitalised Taliban.
In late May, the President had named Stanekzai, a top official in the government body overseeing the country's peace process, to head the ministry.
Stanekzai needed 107 votes from MPs to be approved, but received just 84 out of the 213 who cast votes, dragging out the process of finding a candidate for the post into its 10th month.
"Masoom Stanekzai unfortunately could not get the vote of confidence from the lower house of Parliament," the speaker of the lower house, Abdul Rauf Ibrahimi, told Saturday's session.
"Therefore, we request that the President introduce another candidate for the defence ministry post as soon as possible," Ibrahimi said.
Ghani's previous pick for the post, former Afghan army chief of staff Sher Mohammad Karimi, was also rejected by the lower house in January.
The repeated delay on the appointment is reportedly due to differences between Ghani and his chief executive and former presidential election rival, Abdullah Abdullah, over their choice of candidate, with many linking the leadership vacuum to a recent uptick in deadly insurgent attacks.
The empty post has stoked fears of instability in the troubled nation after NATO troops pulled back from the frontlines in December last year after 13 years of conflict against the Taliban.
The Taliban's "spring offensive" is in full throttle across the country, and marks the first fighting season in which Afghan forces are battling the insurgents without the full support of US-led foreign combat troops.
A NATO combat mission formally ended in December but a small follow-up foreign force of about 12,500 mainly US troops have stayed on to train and support local security personnel.
The Taliban, bolstered by battle-hardened Central Asian fighters in their ranks, recently captured district headquarters of Chardarah, adjoining Kunduz city, triggering fears that they would overrun their first provincial Capital since the 2001 US invasion of Afghanistan.
The militants also launched a brazen assault on the Afghani Parliament in late June that witnessed gunfire and explosions, and sent lawmakers scurrying for cover.
The defence post is not the only one with which Ghani has had trouble: In April, Afghanistan's Parliament had approved 16 cabinet nominees, including four women, but only after months of delays.
