Barack Obama has taken the extraordinary step of publicly releasing his complete birth certificate in an effort to kill off conspiracy theories that have bedevilled the US president since the 2008 election.
“Birthers” believe that Mr Obama was born in Kenya and that his family, including his maternal grandparents, conspired to issue fake birth announcements in Hawaiian newspapers so that their African grandson could become an American citizen. Only US-born citizens can be president.
Mr Obama said he was moved to release the information because the continuing debate was distracting the nation from the serious problems it was confronting, including its long-term deficit reduction plans and rising petrol prices.
