The hon. Gentleman is a keen campaigner in the area of unpaid work trials. As I have said on many occasions, in most cases, unpaid work trials, if they are not a small trial that is conducive to the work environment, are illegal. On the back of his campaign and work that had been done before, we issued new guidance in December 2018. As I have said, where a worker feels that they have had a detriment, they are to report it to HMRC or ACAS. HMRC will investigate every complaint. We cannot just judge this issue on prosecutions. We need to judge it on where the detriment to the worker is, and then ensure that they get what is owed to them and that the employer is penalised.
