There has been a general decline in European jobseeker interest in British jobs, with Ireland recording the sharpest decrease in jobseeker interest, down 44% since 2015, according to figures released by global job site, Indeed.
The study, by Indeed's economic research unit, found that from mid-2015 European jobseekers as a whole became less interested in UK jobs.
Poland was second only to Ireland in recording the sharpest decline in jobseeker interest, down 26%, however by contrast, demand for UK jobs held up well among Italian, French and Spanish candidates.
Some sectors are more affected by this decline, with healthcare and construction roles hardest hit.
One in ten doctors in English hospitals is an EU national, as are 10% of UK construction workers.

In London, nearly a third of builders are EU nationals, according to official figures.
Ireland accounted for the largest share of clicks of all European countries for construction jobs on Indeed.com, followed by Romania and Poland.
The UK construction sector has seen its share of European job inquiries tumble by almost half since 2015, down 42%, while European searches for UK healthcare jobs on Indeed fell by a fifth.
At the same time however, Europeans looking for jobs in technology, finance and languages have not been put off by Brexit just yet.
This suggests that Britain could keep its position as a global tech and banking magnet in a post-Brexit world, provided that its migration policy is sufficiently flexible to accommodate an internationally mobile workforce after its departure from the EU.
Nevertheless, the waning popularity of Britain as a destination for European workers will sound alarm bells for the UK's most "Brexit-exposed" employers.
Indeed's analysis of the Labour Force Survey shows the high-skilled profession most reliant on European expertise is veterinary science, with 21% of UK vets being nationals of another EU country.
Pawel Adrjan, Economist at Indeed, said, "As the closest neighbour, Irish workers have been drawn to the UK for decades and play a key role in sectors from finance to construction and nursing to technology.
"It's no surprise in light of Brexit-related uncertainty that Ireland has shown the largest decline in jobseekers in that market.
"By showing who is searching for jobs and where, Indeed's job search data gives a powerful snapshot of what the future holds for Britain's labour market."
