Kate Garraway clashed with Angela Rayner MP as they spoke about Sir Keir Starmer during Friday's Good Morning Britain.
Kate and her co-host Ben Shephard invited Ms Rayner onto the ITV breakfast show to discuss the resignation of Prime Minister Boris Johnson.
Referring to the opposition, and Labour Leader Mr Starmer, Kate said: "Yesterday he was pictured at Wimbledon having a lovely time, I'm sure that was in the diary for a long time too. Was it wise though for him to be doing that as the government was imploding?"
