Under-fire BBC presenter Naga Munchetty has a reputation for going 'ballistic' at junior staff, and humiliated an intern who didn't make her porridge perfectly, a source has claimed.

An insider, who previously worked with Naga, 50, on BBC Breakfast, revealed the TV host is 'an absolute nightmare', adding that she would 'kick off about the smallest of issues'.

It comes as sources revealed Naga could face a probe from BBC bosses, and has been placed 'under review' amid claims bullied a junior colleague on the flagship morning show.

An insider told The Daily Mail: 'She's an absolute nightmare. She has a reputation for going at young members of staff and making them out to be fools.

'She would kick off about the smallest of issues, including one time she went ballistic over her breakfast not being prepared exactly how she likes it by an intern.'
