( CNN ) -- Yemen will swear in its new president Saturday , cementing a power transfer deal reached in November to end months of protests and violence over outgoing leader Ali Abdullah Saleh 's longtime rule . Abdurabu Mansur Hadi -- who served as Saleh 's vice president and then became acting president in November in an agreement brokered by the Gulf Cooperation Council -- is expected to be sworn in Saturday in front of Yemen 's parliament . On Monday , a formal inauguration will take place in Sanaa -- one that Saleh is expected to attend . A spokesman for the country 's embassy in Washington said late Friday that the president has returned home , after a short U.S. visit for medical treatment . `` As of Saturday morning , Hadi will be Yemen 's president and the inauguration on Monday will only be ceremonial and a celebration in support for Yemen 's new leader , '' said Abdul Aziz Jubari , a member of Yemen 's parliament from Saleh 's General People 's Congress party . Hadi received 99.8 % of the 6.6 million votes cast in Tuesday 's election , according to Mohmmad Hassan al-Hakimi , chairman of the Supreme Committee for Elections and Referendum . Saleh was wounded in a June assassination attempt at his presidential palace during battles between government troops and tribal fighters . A `` massive celebration '' was being planned for Saleh , who will not necessarily disappear from Yemeni politics , said Abdu Ganadi , a senior Saleh aide . `` Saleh has the option to continue involvement in politics and the power transfer deal will not force him to step aside , '' Ganadi said . `` He is the leader of the GPC and his voice and support will continue being heard in the GPC . '' U.S. Secretary of State Hillary Clinton called the Yemeni election `` another important step forward in their democratic transition process . '' Human Rights Watch has called on Hadi to make changes without delay . `` Yemen 's potentially historic transition will be off to a shaky start unless Hadi makes an immediate break with the abuses of the past , '' said Letta Tayler , HRW 's Yemen researcher . `` Yemen 's new leader needs to move decisively to usher in promised reforms that uphold human rights and the rule of law . '' The 65-year-old Hadi is a British- , Egyptian- and Soviet-trained army officer , recently promoted to field marshal . He had been vice president since 1994 and ran for a two-year term as president on pledges of improving security and creating jobs . But he 's never had much of a power base , and Yemen 's problems are expected to take longer than two years to fix . Yemen is the poorest country in the Middle East , with a severe shortage of water and rising levels of malnutrition among its population of about 25 million . Saleh faced a separatist movement in the south , sectarian tensions in the north and the growing presence of what Western officials describe as al Qaeda 's most dangerous affiliate , al Qaeda in the Arabian Peninsula . CNN 's Mohammed Jamjoom , Jamie Crawford and Kindah Shair contributed to this report .
