Pakatan Harapan de facto leader Anwar Ibrahim has urged the coalition's leaders to stop fighting with each other immediately.
Instead, they should focus on developing the economy and making life more comfortable for the people.
"Open fighting among us or within a party must stop immediately.
"I urge that ties within Harapan be strengthened through party channels.
"The people are always watching us, and we only have a little room and opportunity to prove that Harapan can truly change their and the country's fate," Anwar said in a statement today.
The PKR president's remarks come as Harapan leaders trade barbs with one another over various issues.
One of the internal battles being fought now is over whether de facto unity minister P Waythamoorthy should resign following the death of firefighter Muhammad Adib Mohd Kassim.
There have also been arguments over Bersatu's friendliness towards Umno defectors who wish to join the party.
Anwar himself has been hit by internal criticism, after PKR member Latheefa Koya accused the party president of practicing nepotism and cronyism when selecting state PKR chiefs.
