According to this FOI Tower Hamlets have not yet worked out changes to the communications service.
However John McDermott and Helen Watson were supposed to work something out in April 2015. Tower Hamlets really should get it's act together.
This blog will keep people updated with the real events that are happening in Tower Hamlets. It is called Horror Hamlets as a joke but good and bad comments are welcome. You can email me firstname.lastname@example.org.
