The prognosis is very positive and I’m hoping to be back with you in October. Revealing his stand-in, he added: "Until then I've been told to give my voice a rest and leave you in the mostly capable hands of JK and Amanda. Big thanks to them and all the Global family who have been unbelievably supportive.

Be thankful for this day, and when I next see you, I’ve got a great story to tell ...
