I can see that would be really tricky to dig out, owd. I think I would cut it down a bit further, then saw vertically through the middle, right down and through the crown/rootball, then try and cut/wriggle out the half stump and roots farthest away from the rose. You could then sever as much of the remaining roots as possible with stong loppers, leaving any trailing roots near the rose in situ - orphan root pieces severed from the crown should rot down eventually. Don’t know whether that is feasible, the rootball may just be too big..
Mountainous Northern Catalunya, Spain. Hot summers, cold winters.
I have used a product called Spectricide Stump Remover Granules previously to some success. You bore holes into the stump, dump the granules into the holes, and then pour hot water in to dissolve the granules. It's not an immediate fix, but it is supposed to speed up decomposition.
I say "some" success because my stumps are still present a year later, but they have stopped putting out new shoots. The ones I dealt with were quite dense wood, though, and it was difficult to get deep holes in the stumps for fear of burning up my drill's motor. You may have better luck with a softer wood.
Thanks @Nollie & @SYinUSA It's a strange one as the trunk/stump is not a dense wood as would normally expect, but is fibrous. I can easily imagine that it would not transmit sap to regenerate from higher up the trunk but will regenerate from the crown if at all. Likewise, I'm not entirely convinced that the trunk will transmit a chemical killer down to the root. I had left a little height in it temporarily for leverage Nollie, I dug down around it to about a spades depth and it wouldn't budge at all, not a bit. It's very well anchored. I think I may have to resort to a combination fix and cut it as low as I can get, then apply a chemical killer to the crown root. As long as it stops any regeneration, I am not concerned about the stump and root remaining. thanks all for your input
@Meomye, I actually use an old toothbrush and use it neat on cut stumps. Then I possible I cover the stumps with bits of old compost bags, turned inside out to keep the rain out.
I find that to be a decorative feature... I think I would put a pot on top with a trailing plant.. or if I could plant something in a hole, like an herbaceous clematis, scented, 'Aromatica' which only grows a few feet and let it scramble over it..
A bird bath, even..
Any regrowth I would pick out to stop photosynthesizing.. so eventually would die off..
Thanks @Marlorena, Stipa Tenuissima. There is also panicum and miscanthus in that border which will be along later, but my magnolia is the star performer in spring. I can't resist posting pics of it on a day like this.

I like the precision of control over unintended consequences that it suggests.

Just an alternative.. I rather like stumps..
thank you for that.
Lovely garden.
