Tang, who has spent 16 years at NHS England, was also appointed chief digital information officer on an interim basis on 1 April 2025 following the departure of John Quinn. 

In an email, Tang said the time ‘feels right for me to take some time out before embarking on a new challenge'.

She added: ‘I have genuinely loved my time at NHS England – from building a world-class data and analytics function, launching the Data and Analytics Academy, delivering the ambitious NHS federated data platform, setting out the vision for analogue to digital in the 10-Year Health Plan, and mobilising the single patient record, to name but a few things –  these achievements have laid the foundations for a more connected, insight-driven NHS for patients.'

She adds: 'The past few months have shown real promise on how we can work across digital, data and technology we have been engaging with the national programme teams to input to the vision and ambition to transform these services, showing the art of the possible if we embed digital, data and insights at the outset.'

Tang will work with Jules Hunt, interim director general for technology, digital and data, and her senior leadership team to transition her work.

She added: ‘Although the organisational context remains uncertain and challenging, these are undoubtedly exciting times.

‘Collectively, the work you do will help to realise the three big shifts over the next decade, this includes the NHS App becoming the single, digital front door for citizens, the NHS federated data platform and single patient record streamlining how care is provided and empowering patients, our analytics team will ensure the NHS is more transparent than ever before driving improvement, AI expansion will reduce administrative burdens, speed-up clinical workflows and ultimately enabling more patients to receive the care they need and have a better experience of doing so.'
