ISLAMABAD (DAWN/ASIA NEWS NETWORK) - The mantle of the Pakistan Muslim League (PML-N) leadership has apparently been passed on to the younger Shahbaz Sharif, the ubiquitous chief minister of the country's most powerful province, but the real power continues to lie with the elder Nawaz Sharif endorsed by the party as its "Quaid (leader) for life".
Notwithstanding the recent court ruling, Nawaz Sharif stays at the helm of the ruling party.
Indeed, the nominal change became unavoidable after the apex court struck yet again, barring the former prime minister from leading the party.
The elevation of Shahbaz Sharif has also been necessitated not only to meet the legal requirement, but also to maintain unity within the party as the general election approaches.
However, Shahbaz Sharif's ascendancy is not likely to tilt the balance of power within the ruling party to the other branch of the family as is being anticipated.
It is hard to envisage how much influence and power the younger Sharif could have under the overwhelming shadow of his elder brother that is not going to fade away and the niece who has emerged as the party's populist face of defiance.
In this situation, Shahbaz Sharif will just be a figurehead in his capacity as the party's interim head.
He had come very close to being crowned when Nawaz Sharif was unceremoniously removed from the country's highest public office that caused him to be stripped of the party leadership too.
But an amendment in the electoral rules restored Nawaz Sharif's presidency.
The latest court decision against him has, however, changed the situation yet again.
So the dice is cast in favour of Shahbaz Sharif though it is not to the liking of the dominating side of the family.
The political cleavage between the two Sharifs is too obvious to ignore and may further intensify with the impending court decision in graft cases against Nawaz Sharif and his family, likely to be announced in the next few weeks.
Given the stand-off between Nawaz Sharif and the judges, it seems rather improbable that the former prime minister can emerge from the trial unscathed.
The most serious concern for senior party leaders at the moment is how to stop the party from fragmentation.
Under the circumstances, Shahbaz Sharif appears best placed not only to lead the party, but also to be a candidate for prime minister if the PML-N returns to power in the coming elections.
But it will still be Nawaz Sharif calling the shots.
This dichotomy of power within the party may have its own perils.
The differences between the two Sharifs are too serious to be resolved, especially as there is no sign of the former prime minister backing down from his confrontational position.
A big question, however, is whether the mercurial and extremely temperamental leader who may have proved a good administrator at the provincial level can also deliver on the national stage.
Shahbaz is not a charismatic and populist figure who can lead the party to an electoral victory without his older and more popular brother on his side.
In such a situation, he will have to walk a tightrope balancing his moderate approach and Nawaz Sharif's confrontational politics.
Meanwhile, Shahbaz Sharif has also been overshadowed by the rising populist image of Nawaz Sharif's daughter Maryam, who has emerged as the main crowd puller at PML-N rallies.
Even PML-N leaders sceptical of her aggressive stance towards the judges and the security establishment concede that her relentless campaign has infused new life into the party and kept it afloat.
So it may not be smooth sailing for the pretender to the throne as the party ranks are torn between two conflicting approaches.
While most potential party candidates in the coming elections may not support the clash of institutions that could jeopardise the polls, they also know that they need Nawaz Sharif and his daughter to win the votes.
The development work done by the Shahbaz government alone would not help ensure victory for the PML-N in the battleground that is Punjab.
Notwithstanding Sharif's defiance, the challenges for the ruling party are getting more serious.
The Election Commission of Pakistan's move to keep the PML-N out of the Senate elections following the Supreme Court's order declaring all decisions of the party taken under Nawaz Sharif's presidency illegal has shattered the party's hope of achieving a majority in the Upper House of Parliament.
The candidates put up by the PML-N can stand as independents and join any party after winning the seat - it is not sure how many of them would stay loyal.
After the Balochistan experience when loyalties changed overnight, horse trading cannot be ruled out in the Senate elections.
Meanwhile, the latest crackdown by the National Accountability Bureau (NAB) on senior provincial bureaucrats on graft charges has come as a serious blow to the chief minister of Punjab who boasted about good governance and claimed running a corruption-free administration.
The action taken by NAB sends a clear signal that the noose is being tightened around those civil servants considered close to the chief minister and the PML-N.
It is the first time that NAB has become active in Punjab targeting senior government officials. This raised questions about the timing of the action of the anti-graft body.
Many ruling party leaders tend to establish a link between the judicial action against the Sharif family and the NAB crackdown in the ruling party's political stronghold on the eve of the general elections.
Undoubtedly, the NAB crackdown has provided ammunition to the opposition parties to target Shahbaz Sharif and the Punjab government.
But one is not sure whether this clampdown would hurt the ruling PML-N vote bank in the central Punjab that seems to have remained intact or may have even increased after the judicial actions against Nawaz Sharif.
Although Shahbaz Sharif has finally been installed as party chief, the move is not likely to change the power structure within the PML-N, with Nawaz being declared as supreme leader.
Still, things may change dramatically in the next few weeks with the possible conviction of the Sharif family.
