My hon. Friend raises a most important point. A priority is to provide consistent, multi-agency support to people who are courageous enough to come forward. Of course, the police lead on that. That support enables intimidated witnesses to remain safely in their community, if we can build structures around them, but it is not impossible to move someone if that is essential. At court, special measures have been introduced to help vulnerable and intimidated witnesses, such as giving evidence from behind screens, and being able to testify by television link from a place that could be some distance away from the court. About a third of witnesses would not have been willing or able to give evidence if those measures had not been available; that seems to be testimony that they are working quite well.
