Exclusive The UK Home Office is contemplating "a complete or a partial shutdown" of its ambitious programme to shift blue light services off radio and on to 4G, The Register can reveal.

The Emergency Services Mobile Communication Programme (ESMCP) was supposed to replace the Motorola-owned Airwave radio service with a £1.2bn 4G Emergency Services Network (ESN) run by EE. It also intended to kit out emergency services with 4G-enabled devices ahead of Airwave being switched off by 31 December 2019.
