International Desk: US President Barack Obama says he has advised his successor Donald Trump not to attempt to run the White House "the way you would manage a family business".
The outgoing President said he has been in regular communication with Mr Trump, who will be inaugurated in less than two weeks.
In an interview with ABC News, Mr Obama said that Mr Trump must "respect" US institutions.
Mr Obama said the President-elect must understand the difference between campaigning and leading a country.
"After you have been sworn in," he said, "you are now in charge of the largest organisation on Earth".
"There are world capitals and financial markets and people all around the world who take really seriously what he [Mr Trump] says," Mr Obama said.
