Doblo 1.2 petrol wont start

Fiat Doblo 2004 1.2 Petrol - Wont Start or even turn the starter
Battery is good had checked in garage, Fuel in the tank.

When I put the key in Ignition - first click, the ignition lights come on, Battery light flashing and low level clicking noise from behind the Dash.
When I turn key to start nothing happens Starter does not even try to click or turn.

I did try jump leads from a 1.9 Vectra, still nothing.
Any Ideas or suggestiosn so I can try rule out any other problems. Car started fine this morning but will not start at lunch.. ?Very Strange.
Im thinking maybe a relay problem or a electrical Issue.. Pleas HELP.

I should imagine if it is high miles, the starter could be done.

Or it may be a bad earth (body/battery to gearbox).

Easy to check if it's the earth, simply attach a black jump lead from the battery negative - to somewhere on the engine such as a lifting bracket or a metal component and see if she will turn over.
