With the CIA concluding that Russia intervened in order to help him win the White House, Donald Trump has claimed that if he lost the election and made similar accusations they would be dismissed as a "conspiracy theory".

Calls for a Congressional investigation into Russian hacking during the election, now joined by leading Republican senators, have been met with anger by the president-elect and his advisers.

Mr Trump denies that the CIA could know it was Russia who hacked the Democratic National Committee and John Podesta, Hillary Clinton's campaign chairman, despite the consensus among intelligence officials that the Kremlin was responsible.
