Dr Hilary Jones has been doing a heroic job keeping the nation informed on Good Morning Britain.
But, after two months, he's taking a well-deserved week off from the breakfast show.

And on Tuesday morning, Dr Mark Porter joined Ben Shephard and Charlotte Hawkins.

Who is Dr Mark Porter?
Dr Mark is no stranger to a TV studio but, like Dr Hilary, he is a practising GP and spends half his week at his practice in the Cotswolds.
The rest of the time, he concentrates on his journalism and broadcast career, which includes fronting BBC Radio 4’s medical series Inside Health.
He has been appointed MBE for services to healthcare, and has received the Healthwatch-UK Award for his contribution to public understanding of evidence based medicine.
