BBC Breakfast is in crisis because Naga Munchetty and other presenters apparently no longer speak to their 'loathed' boss, it was claimed today.

Naga is also alleged to have fallen out with her co-host Charlie Stayt amid tensions behind the scenes on the 'cosy' morning show.

The BBC has launched a bullying probe into its flagship morning show, which has been branded 'toxic' behind the scenes in yet another crisis for the Corporation, it has been claimed.

In April, MailOnline exclusively revealed some staff had expressed unhappiness with the show's bullish editor Richard Frediani, accusing him of being on occasion 'aggressive' and 'belittling' towards his underlings.

Now, tensions are said to be 'rife' between hosts Charlie Stayt and Naga Munchetty, who has already expressed her uneasiness about Frediani's behaviour.
