Mr Obama is also planning executive orders that do not require legislation on his first day in office, which could include plans to promote renewable energy resources and create jobs.

His transition team, which is reportedly much more extensive and active than Mr McCain's, features 10 working groups in different policy areas to convert campaign promises into concrete legislation. It is chaired by John Podesta, Bill Clinton's former White House chief of staff who runs the Centre for American Progress, a think tank long seen as a Democratic administration in exile.

Mr Podesta is working closely with Michael Signer, a former foreign policy aide to John Edwards in charge of homeland security affairs. Mr Podesta and Jason Furman, one of Mr Obama's two most influential economic advisers, have already held talks with sceptical conservative Democrats to line up the votes to pass a stimulus package.
