Doctor strikes going ahead. A poor decision. I have never striked for a single minute in my fifty plus year career in medicine, and I never will.
I’ve been a doctor for over 50 years, and I am appalled by the strike. telegraph.co.uk/news/2025/07/1…
Doctors should stop striking and start treating patients.
At US National Proton Conference in Philadelphia - amazing enthusiasm for proton therapy. I seem to be the only person from the UK here!

Abolishing NHS England and returning power to local trusts is a very welcome move. Full credit to @wesstreeting. I am impressed!
It undermines those actually struggling with dementia. It’s a cruel illness, should not be used disingenuously to discredit.
I’ve known Rupert for ten years, working very closely with him. I have never seen any signs of any decline. To use dementia as a weapon is possibly the most disgraceful thing I’ve seen in politics. It really is nothing to smirk about. Despicable behaviour from Reform.
When asked if I have dementia, Tice says "I've no idea", "ask him". You're disgusting, @TiceRichard. I've known you for years. You know full well that I do NOT have dementia. It's a sickening rumour, weaponising a cruel condition to smear my name. You should be ashamed.
Politicians should stop referring to the NHS as 'our NHS'. It's not a religion, it's a health service - a poorly performing one, at that. Stop treating it like a god.
Five years ago. This did not save a single life, but ruined millions of childhoods for months and months. Absolute madness.

What on earth is going on in Britain?

Five years on, can we please finally remove these COVID relics that stain our towns and cities?

A final #BrainTumourAwarenessMonth reminder of some common signs and symptoms of brain tumours - to remember this month, and all year round!👇
My last book published today - eight editions in thirty five years. There has been fantastic progress in how we treat cancer over that time. The NHS can deliver world class care, but fails many patients through delays, rationing and poor access. Britain deserves better!

My last edition comes out tomorrow, eight over thirty five years is not bad... An honour! routledge.com/Treatment-of-C…
