This is high on the news agenda at the moment but I haven't heard or seen any of the reports stating who is responsible for doing the work and is therefore going to draw in all that extra spend:
`Home Office failing on Emergency Services Network, says NAO: The delayed Emergency Services Network is slipping further behind schedule and is getting more expensive all the time – and the Home Office’s management of the project is to blame, says the National Audit Office'
After searching the web I eventually found a report in Computer Weekly
LINK which tells us this:
`There are also a number of commercial risks – renegotiation of the main ESN contracts with key suppliers EE and Motorola are falling further behind schedule, and Motorola’s acquisition of Airwave [the present system] at the end of 2015 has complicated these talks, to the extent that there is now a clear risk that Motorola would financially benefit from further delays if they cause more extensions to the Airwave contract.'
..and this:
`Also, said the NAO, the overall delivery of the programme would ultimately depend on emergency services being satisfied that it was a suitable replacement for the Airwave network. However, many bodies have expressed serious concerns that the coverage and resilience of the EE ESN network will not match Airwave.'
