Tapper up, King down:

CNN chief national correspondent John King could be ousted from the network in favour of new Chief Washington correspondent Jake Tapper, MailOnline can reveal.

King, 49, has already moved out of his office to make way for Tapper, 43, who was poached by new CNN boss Jeff Zucker from ABC.

And now sources have revealed that King has not signed a new contract - and has instead signed an extension to his existing deal, leaving his future at the network unclear.

This is what's known as "trading up."

There was nothing spectacularly wrong with King, but he did occupy that charisma-free zone where so many of CNN's correspondents reside. And Tapper is (usually) one tough, smart reporter.

Good move, CNN. Let's see more like this.
