Jordan's Prime Minister Bisher Khasawneh submitted his resignation on Sunday less than week after a parliamentary election that saw some gains for the opposition.
Jaafar Hassan, now head of King Abdullah's office and a former planning minister, is expected to replace Khasawneh, a veteran diplomat and former palace advisor who was appointed nearly four years ago, the officials told Reuters on condition of anonymity.
Hassan will face the challenges of mitigating the impact of the Gaza war on the kingdom's economy, hard hit by curbs to investment and a sharp drop in tourism.
The outgoing prime minister had sought to push reforms pushed by King Abdullah to help reverse a decade of sluggish growth hovering at around two per cent that was worsened by the pandemic and conflict in neighbouring Iraq and Syria.
The Muslim Brotherhood opposition and ideological allies of Hamas made significant gains in Tuesday's election, boosted by anger over Israel's war in Gaza.
The new composition of the 138 member parliament retains a pro-government majority, but a more vocal Islamist-led opposition could challenge IMF-led free-market reforms and foreign policy.
