"The NHS for example, we wouldn't be able to sustain our healthcare if it wasn't for the talent and the skills that is coming over from the continent." Petros Fassoulas, Chair of European Movement
"If you take Petros's example about we wouldn't have a health service, the health service is largely run by people who we now try to restrict coming into this country because they're actually Commonwealth countries." Frank Field MP
In the wake of last week's European elections, the Today programme this morning discussed the future of free movement of people within the EU. The discussion turned to the importance of EU migrants to the NHS, and how this compares to that of migrants from other countries.
It's impossible to measure the 'importance' of foreign nationals to the NHS per se, but we can look at the numbers it employs on permanent contracts.
Figures from September show the proportion of NHS workers - excluding GPs - in England recorded as British was 78.5%. The proportions of staff from other EU and Commonwealth member countries were relatively similar to one another; 3.6% were nationals of EU countries and 4% were nationals of Commonwealth countries.
Most NHS staff in England are British nationals
The numbers we've looked at are 'full time equivalents', a measure of the number of staff based on how many hours are worked.
The data tells us about the nationality of staff, not how many have migrated from other countries, because many migrants will have become British citizens.
Information on nationality was available for 88.6% of staff covered by the data. The rest were recorded as having an 'unknown' nationality, so the true proportion of EU and Commonwealth NHS workers might differ slightly from what is officially recorded.
Cyprus and Malta are members of both the EU and Commonwealth; the restrictions on entry that Mr Field was talking about don't apply to them, so we've excluded them from the grouping of Commonwealth countries.
We've also broken the same data down by whether staff have clinical qualifications. Staff with the qualifications include doctors, nurses and therapists among others, but not secretaries or managers. Of those with clinical qualifications, 4.4% are EU nationals and 5.4% are Commonwealth nationals.
Update: 30 May 2014
We've updated the piece to reflect the fact that the data is on permanent rather than temporary employees, and doesn't include GPs.
