Webster, who has more than 35 years of experience in national and local roles in health and care - more than half as a chief executive in the NHS, has led the West Yorkshire Health and Care Partnership since its formation in 2016 and has led the ICB since its formation in 2022.
He said: ‘I believe it is time for someone else to take the organisation forward as it transitions into a new organisation, with a new role, within a new system.'
Webster added: ‘This has been a difficult period for everyone in the health and care system. I am proud to have worked with all of you and have seen - over and over again - how you exemplify public service.
‘I know the new ICB will develop and adapt to become an extremely important part of the future emerging health and care landscape, building on firm foundations we have created, together.'
Professor Nadira Mirza, acting chair of West Yorkshire ICB and acting deputy chair of the West Yorkshire Health and Care Partnership, said: 'Rob has been instrumental in the development of our collaborative approach and our success as a partnership. So much great work has and continues to take place across West Yorkshire, focused clearly on addressing and reducing health inequality. Rob has always led with a very clear focus on making sure that everything we do has patients, members of the public at the heart of everything we do.
'Whilst the months ahead will be a very challenging time for the ICB, the West Yorkshire Health and Care Partnership and indeed the wider NHS, we must continue to work with the board, wider partners, local communities and staff across West Yorkshire to respond to and deliver the 10-Year Health Plan, using the rich and diverse insight we have about our patients and communities across West Yorkshire.'
