Dozens fewer civil servants are being employed in north Nottinghamshire following the Brexit referendum, despite ranks swelling by tens of thousands elsewhere in the country.
It comes as a leading public sector union has called for an urgent meeting with the Government, to discuss the impact of no-deal planning on civil servants across the country.
Figures released by the Cabinet Office show there were 910 people employed by the civil service in the north Nottinghamshire area at the end of March this year.
This was a decrease of five per cent compared to March 2016 – just before the referendum – when there were 960.
Civil servants are those who work for government departments, agencies, and non-departmental public bodies, such as the Equality and Human Rights Commission.
It does not include people who work for local councils, or in public bodies such as the police or NHS.
Civil servant numbers have soared across the UK since 2016, with more than 445,000 now employed – including 4,860 deployed overseas.
That's an increase of almost 27,000 in just three years, following a sustained decline prior to 2016.
A spokesman for the Cabinet Office said the increase could be for a number of reasons, with the cross-departmental nature of the civil service meaning it is difficult to determine if people had been recruited specifically for Brexit planning.
However, the Institute for Government think tank said recent trends in recruitment – particularly outside of London – showed signs of Brexit preparations.
A spokesman said: "The largest increases in the first three months of 2019 were at the Home Office and HMRC – two large departments that are more evenly spread across the UK, which will be key in delivering changes to how the UK border operates after Brexit."
"This suggests that the focus of Brexit recruitment is starting to shift from policy to operations."
The civil service headcount in north Nottinghamshire had been falling prior to the Brexit referendum – in 2015, it had stood at 1,010, before dropping to 960 in 2016.
Of the 168 geographical NUTS areas in Great Britain, 70 have seen an increase in civil service employees since 2016 – only four of which are in London.
A spokesman for the Public and Commercial Services Union (PCS), which represents civil servants, said its members were concerned about the impact of Brexit on job changes and workloads.
He said: "PCS has consistently criticised the lack of planning for Brexit over the last three years, and called for extra resources to be made available in the civil service to carry out the work needed to deliver Brexit.
"Staff have been redeployed to departments that are suffering from staff shortages because of their Brexit workloads.
"Planning has been far too last minute and chaotic."
A Cabinet Office spokesman said: "The civil service is delivering this Government's commitment to leave the EU.
"To do this, we are equipping ourselves with the right people and skills across government to make this happen.
"At the same time, the civil service continues to make sure that all of the priorities of the Prime Minister are being delivered."
