Material shows differently in Edit and Object mode

Hi Guys,

I’m trying to get my head around why my material might be misbehaving?
In Edit mode it shows it exactly as I want the material to look.
However when I Tab into Object mode I see something completely different.
Why is this?

I have attached the Blender file if someone could help me out with this.
Thanks
Phil
