Just taken the forks out in order to replace bearings. Is the cone just above the forks removable.? Feels as if its part of the forks.

    Should be - although that is a mess. It looks like it's well stuck. Try some decent penetrating fluid and then carefully tap it off.
    I'm left handed, if that matters.

    That looks nasty.

    yeah, nasty, looks like galvanic corrosion

    there could be two bits stuck on there, try plusgas to penetrate, though i think it may not help much, in spain i've seen combined freezing/penetrating spray, that might be more effective as the aluminium will contract slightly more than the steel, must be available in uk too

    other ideas...
    an lbs should have a crown race removal tool which avoids impact

    or use a dremel to cut a notch almost through, then spread the notch with a screwdriver to snap the thing off

    the corrosion bubbling the paint the at the top of the forks is bad, the lettering says 'carbon' but the steerer at least is aluminium, it could still be ok, but if there's corrosion where there's an al-al or al-cf bond then seriously consider binning them, a failure at that point would be extremely dangerous

    The bonded part is a lot further down though - about where the OCLV logo is.

    That's just the paint bubbling. I would want to remove the brake and grease the bolt though because the chances are it's well stuck too.
