Question to the Home Office:

To ask the Secretary of State for the Home Department, whether he has made an estimate of the (a) number and proportion of permanent staff in the National Crime Agency's International Corruption Unit who were in the unit for more than 12 months and (b) staff attrition rate from that unit in the last two financial years.

The International Corruption Unit (ICU) is the dedicated team within the NCA that investigates serious criminal allegations of bribery and corruption.

We are unable to disclose the number of staff employed in the ICU as that information is operationally sensitive. However, in 2022/23, 86% of staff had been in the unit for more than 12 months. In 2021/22 it was 84% of staff.

The ICU staff annual attrition rate was recorded at 5.5% in both 2021/22 and 2022/23.

Due to complexities on deriving the figure, the NCA is unable to provide the average years of staff service.
