Thanks v much for your help.
I was able to remove it easily once I realised the warning sign holder
needed removing.

On other matters I noticed that when I throttled down off the motorway I had
lost a lot of power.
Almost as though the car wasn't running on all its cylinders, I could even
floor it and only get a little acceleration.
However, after stopping and driving later than evening the power returned.
It seems connected to longish drives at high power causes the problem.
