My hon. Friend makes a very good point. British Transport police is doing good work in this area, and the Home Office is providing £25 million of targeted investment over this year and next year to tackle this particular issue, £5 million of which is already in operational use. Overall, expanding the national county lines co-ordination centre will be very positive in getting results, including work with British Transport police to prevent disruption on the rail network. There is also investment in new technology, including automatic number plate recognition. We are working across the board with law enforcement agencies and partners to deal with these gangs.
