Focus not starting

[norfolk lifestyle]

Have a 2011 Focus auto diesel which has suddenly decided to not start. Everything works as it should except no response when start button is pushed. Car recognises the transponder and it comes out of park as it should. No power at the starter relay. if we bridge out the relay, the starter engages but car will not start. Was working fine prior to stopping for lunch. Car is on Norfolk Island so a visit to a dealer is not an option. Any advice would be really appreciated
