To ask the Secretary of State for Justice, how many prison guards were formally investigated for conveyance of (a) drugs, (b) weapons, (c) tobacco and (d) other illicit material in each year since 2015.

It is not possible to break down the charge of trafficking into the specific categories of drugs, weapons, tobacco, or other illicit material in our departmental-wide data.

The vast Majority of Prison Service staff are hardworking and honest. A minority of staff engage in corrupt activity which is often as a result of conditioning and manipulation by prisoners, and we are doing more than ever to catch the small number who break the rules. We drive a culture of the highest professional standards, and we are committed to addressing wrongdoing sensitively and fairly, preventing it escalating into corruption. Where corruption does take place, however, we provide a robust response.

This is on top of robust vetting procedures, including criminal record checks, while our £100 million Security Investment Programme aimed to improve security with a focus on technology, such as X-ray body scanners. This endeavours to improve our ability to detect and disrupt drugs from entering prisons, supported by enhancements to intelligence and counter corruption capabilities.
