The British Division of the IAP comprises members from the United Kingdom (England, Wales, Scotland, Northern Ireland), Republic of Ireland, Belgium and the Netherlands. The largest cohort come from the UK and the organisation is based mainly within London at the Royal College of Pathologists and England more widely.

There are strong links with the Pathological Society of Great Britain and Ireland with annual joint meetings and shared offices in London. For these reasons it was felt that we should also have more defined links with the National Societies to demonstrate our commitment to pathology education in these countries.
