On 1 April 2006, 59 HM Revenue and Customs (HMRC) overseas officers with functions including those of a drugs liaison officer transferred to Serious Organises Crime Agency (SOCA). Of those, 50 remain in post to-day.
In line with the statutory responsibilities of SOCA to reduce harm from all forms of organised crime, not just from the threat of drugs trafficking, all of these posts have been converted to SOCA liaison officer posts which are general crime posts.
