The explorer Sir Ranulph Fiennes - who lives on Exmoor - is due to begin treatment for severe frostbite in South Africa.
He was flown out of Antarctica last night after being forced to abandon his latest challenge. He had hoped to be one of the first people to cross Antarctica in winter but his team say the expedition will go on without him.
I have undergone a number of tests on my frostbitten hand both in Antarctica and since arriving here in Cape Town, and I am due to have additional tests here before leaving for the UK.
I feel very lucky to have been treated with the upmost care by extremely well trained professionals and have felt in safe hands throughout.
The warmth of Cape Town seems a million miles from the conditions my expedition partners are experiencing right now on the ice.
Those five men are forever in my thoughts and I wish them all the luck in the world for the expedition ahead.
Under the expert leadership of Brian Newham, I know that they have every chance of pulling off this extraordinary feat and making me and people across the Commonwealth extremely proud.
It is a very difficult and dangerous undertaking, but if there is any one group of people who can do it, it is them.
But now my focus is on returning to the UK, getting well and throwing all of my energy into helping the team there promote our aims, and making sure we raise $10 million for Seeing is Believing as we have set out to do.
