A leading Merseyside physician, who has been made a knight in the Queen's Birthday Honours, said he owes the title to colleagues.
Professor Ian Gilmore, who is president of the Royal College of Physicians, has worked at the Royal Liverpool University Hospital for 30 years.
The consultant gastroenterologist said that the knighthood "recognises the excellent work of the teams around me".
Sir Ian, from the Wirral, is also chair of the Alcohol Health Alliance.
He said: "I am delighted to receive this honour, which recognises my many excellent colleagues in Liverpool as well as the tremendous efforts made by the Royal College of Physicians to improve health and healthcare in the UK and beyond.
"This is done through setting standards, educating doctors, and promoting an environment where people can make choices that promote health and wellbeing."
An honorary professor of medicine at the University of Liverpool, he is also known for his work tackling public health issues including alcohol misuse, health inequalities and the impacts of climate change.
