Piers Morgan has announced he is to interview Larry King - just days after the TV veteran gave a less than glowing review of his successor.

77-year-old King lashed out last week declaring that the ‘Britain’s Got Talent’ judge and former newspaper editor had been “oversold” to US audiences.

He then, according to ‘The Daily Mail’, took a swipe at Morgan’s interview style saying; “he interrupts too much and is not dangerous enough in his questioning”.

In response to King’s claims Morgan tweeted; “Got a feeling we may need to discuss Larry's claim that I'm ‘oversold’ and ‘not dangerous’”

Before revealing King was to be a guest on his show, Morgan also tweeted about who his secret guest might be; “The secret guest has had an incredible life, on and off screen, and I suspect there will be a little tension in the air too.”
