It has been a "privilege and a pleasure" to serve in the role at the RPS, said Mr Soni in a statement:
“It has been a privilege and pleasure to serve the RPS and the profession for the last two years. I am hugely proud of the progress the RPS has made over recent times and that we now have a stronger and more influential voice in pharmacy and healthcare across Great Britain.
“During this time I have met many pharmacists doing fantastic work in all healthcare settings, as well as in academia, the pharmaceutical industry and in many other roles. I hope I have played my part in making sure the stories of excellent patient care delivered through our profession have been heard at the highest levels within the NHS.
“I look forward to working with the new President to make sure the RPS continues on its journey to becoming the Royal College for Pharmacy," he said.
The new President will be elected at the next Assembly working meeting on 19 July.
