Nobel laureate Prof Dr Muhammad Yunus has left for Dhaka from Paris, the capital of France.
He left for Dhaka from Charles de Gaulle Airport on Wednesday.
He was given strict security at the airport by members of the French Special Forces.
Yunus will arrive in Dhaka on an Emirates flight (EK-582) from Dubai at 2pm on Thursday, according to Yunus centre.
Meanwhile, Dr Muhammad Yunus has been acquitted from the prison sentence handed down by the labour court in a case over labour law violations.
The Labour Appellate Tribunal delivered the verdict on Wednesday after hearing the appeals submitted by Dr Yunus and others against the previous ruling, Dr Yunus's lawyer Abdullah Al Mamun confirmed.
Dr Yunus is set to head an interim government following the resignation of Sheikh Hasina as prime minister on Monday in the face of massive protests.
Early on Wednesday, Nahid Islam, a key coordinator of the Anti-discrimination Student Movement, told reporters outside Bangabhaban that the administration of the oath of the interim government would be possible within 24 hours or slightly more.
He said that Dr Muhammad Yunus's name was proposed during the meeting. The President also agreed, saying the interim government would be formed under his leadership.
Thirteen coordinators of the anti-discrimination student movement went to Bangabhaban immediately after 6pm on Tuesday to discuss the country's current situation and the structure of the interim government.
