BBC: The Scottish justice secretary will be forced to defend his decision to release the Lockerbie bomber, as the Scottish Parliament is recalled later.
Opposition parties will demand to know how Kenny MacAskill aims to repair the damage they claimed had been done to Scotland's global reputation.
He has been under huge pressure, after granting early release to terminally-ill Abdelbaset Ali al-Megrahi.
Mr MacAskill will make a statement to parliament and be questioned by MSPs.
The parliament will reconvene at 1430 BST on Monday.
Megrahi was freed after receiving a life sentence imposed in 2001 for his conviction for the UK's worst terrorist atrocity, which claimed 270 lives in 1988.
International standing
The 57-year-old, who has prostate cancer, returned home to Libya on Thursday to jubilant scenes which included people waving Scottish flags.
Scottish ministers said their decision to release Megrahi on compassionate grounds - which has been strongly criticised by the US government - followed due process and was the right one.
As the Scottish Parliament was preparing to cut short its summer break to discuss the issue, Scotland's opposition politicians urged Mr MacAskill to set out how he intends to improve Scotland's international standing in the wake of the criticism.
