Trump promises blizzard of executive orders on first day of presidency

On the eve of his return to the White House, President-elect Donald Trump promised to sign a blitz of executive orders on his first day as president, telling supporters that he would move with "historic speed and strength" in the hours after taking the oath of office.

Addressing a raucous crowd of thousands in a Washington DC arena for a "Victory Rally", Trump offered a preview of the next four years and celebrated his November election victory over the Democrats.

The Republican promised to act unilaterally on a wide array of issues, using his presidential powers to launch mass deportation operations, slash environmental regulations and end diversity programmes.
