Speaker of Parliament Professor Aaron Mike Oquaye has been sworn in as the acting president of Ghana.
It follows the absence of the President, Nana Akufo-Addo and Vice President Dr Mahamudu Bawumia, from the country.
The president left Accra Sunday afternoon to attend the inauguration of George Weah as the President of Libeira.
Bawumia, who should have acted in his absence, is also on a medical leave in the UK after he took ill on Friday.
The President will return to Ghana on Tuesday.
