The number of British personnel involved in an international training program for Ukrainian soldiers has plummeted by over 1,000 in the past two and a half years, newly released figures reveal.
The drop marks a staggering 73 percent reduction in the UK’s staffing of Operation Interflex, the British-led initiative that has trained more than 51,000 Ukrainian troops to resist Vladimir Putin’s invasion.
The sharp decline comes as Britain and its European allies rush to reinforce their defences amid mounting pressure from Donald Trump and heightened concerns about NATO’s readiness.
Government data, revealed in response to a written parliamentary question from Liberal Democrat defence spokesperson Helen Maguire, shows that the number of British personnel assigned to the operation has decreased by 1,020 since June 2022. At its peak, 1,389 UK staff were deployed to support Interflex.
However, by January 2025, only 369 British personnel remained engaged in the program. The figures include personnel assigned to Interflex HQ, training delivery units, and logistical support.
The Ministry of Defence (MoD) insists that the drop in British staff does not equate to reduced support for Ukraine. According to the MoD, twelve other nations have significantly increased their contributions to Operation Interflex, reducing the need for UK personnel. Officials also argue that operational efficiencies have allowed them to sustain the program with fewer resources.
Armed Forces Minister Luke Pollard defended the reduction, stating that “UK personnel numbers alone do not represent output of total personnel”, emphasizing that Albania will officially join the training program at the end of the month. Other countries currently supporting the initiative include Canada, Denmark, Finland, Sweden, Norway, New Zealand, Lithuania, Australia, Romania, Netherlands, Kosovo, and Estonia.
The most drastic staffing cuts occurred under the previous Conservative government, with an especially steep decline between July 2023 and January 2024, when 882 personnel were withdrawn. However, despite Labour’s historic election victory in July 2024, the party has failed to reverse the trend, with staffing numbers falling by an additional 59 personnel since taking office.
Concerns Over UK’s Role in Ukraine’s Defence
The Liberal Democrats have condemned the sharp decline in UK military support, calling it “deeply concerning”. They have urged Pollard to “urgently explain why cuts to staff numbers for this vital program have not been reversed”.
“As we can no longer count on the US under Trump to help Ukraine, the UK needs to lead from the front in supporting their resistance against Putin’s barbarism. That means investing more in critical initiatives like Operation Interflex, not less.
“The Labour government has failed to reverse Conservative cuts, even as a war rages on our continent. The armed forces minister must urgently explain why cuts to staff numbers for this vital programme have not been reversed. Labour needs to take British and European defence seriously.”

The MoD has pushed back against claims that the UK is scaling back its support for Ukraine, calling such accusations “completely untrue”.
The debate over Britain’s role in Ukraine comes amid growing concerns over the state of the UK’s armed forces following years of budget cuts. With Trump’s return to power, pressure has mounted on European allies — including Britain — to increase defence spending.
Last week, European leaders met in Paris to discuss their response to Trump’s shifting stance on Ukraine, fearing a reduction in US support for European defence. The emergency summit followed Trump’s announcement that he would bypass Europe by negotiating directly with Putin on Ukraine’s future.
His position has drawn criticism from top military figures, including former UK Defence Secretary Ben Wallace, who warned that Britain must “step up to fill the void in Europe and show our own leadership”. He also cautioned that a reduced US role in NATO could embolden hostile nations.
Despite concerns, the UK remains a major supporter of Ukraine. Since the war began, Britain has committed £12.8 billion in aid, including £4.5 billion in 2025 alone — more than any previous year. However, critics argue that continued support requires not just financial aid but also sustained military assistance, including training programs like Operation Interflex.
