The RLIF should award the 2021 WC to the UK &I now. Keep the current team in place and start the process now. The 2017 tournament wont be in the UK and is nailed on for Aus/NZ. That means that UK&I probably nailed on for 2021. There will be a huge amount of good will after this tournament and we should jump on that and start planning now.
The added benefit is we can then plan a full international programme around that as well.
