We have found several 'shrub'-like stems/leaves and are convinced we have never spotted them in the garden before. They are coming from thick roots which are an orange/red colour. I checked it via PlantNet which suggests it is Prunus Domestica L.
We have a peach, mature apples, comice pear (grown from seed) and comice pears on a rootstock, quince and medlar. 
Any thoughts, please?

There’s something in my head which keeps saying English Elm suckers when I see the photo … but it’s a good while since I’ve seen one 😢 

Edited to add … think I’m wrong about elm as the leaves in the photo are opposite rather than alternate.

are you about?  What do you think?

look like Plum suckers to me

Is it possible that the peach has a plum rootstock? Sorry if this is a silly question as I know nothing about rootstocks. 😊 The 'suckers', if that is what they are, seem to be in the area of the peach tree.

Not silly at all.

Peach trees are often grown on a Plum rootstock.

Mmm thank you - I'd best get rid of it then?
Thanks for your thoughts everyone. 😊

If you can, try and pull it away in the opposite direction to that which the root is growing (so toward the tree) so it comes away from the root completely.
If you snip it off you'll probably get more coming up from the same place.
Lots of trees produce suckers

Thank you! 😀
