Many use a hammer & punch but this can damage the cap.
If you search Ebay `adjustable peg spanner` or adjustable pin wrench` as the man above supplied a link to there are plenty available for £3+ - you may have to file/grind the pins/pegs to fit?
If you have a workshop/tools make a peg spanner
Spray inside & out with penetrating oil.
Measure distance between the two tool holes.
Mark & drill a flat piece of metal plate at one end to the suitable diameter for two `pins` to go into. Ensure long enough to hold past rim of case.
Insert two pins in plate & engage in the cap holes/slots.
Standard RH thread so the rule `righty tighty, lefty loosey` applies!
I have sockets I have ground to produce a range of primer removal tools.

Whereabouts in the UK are you? I have the proper tools for removing 25pr primers, if you're willing to bring it here.

I think there is a specific tool in the 25 pounder tools for removing the primer.

Ideally, you want one of these -
Then, if the the pins 'cam' out and destroy the slots there is a tool that fits over the magazine of the primer and locks onto the holes, so it can be unscrewed from the inside - so to speak. (The latter may well have been of ARMADU 'local manufacture.')

How old is your 25 Pounder case? I believe only post-war cases had primers with flash tubes.
I have removed a smaller primer before now with a length of hollow steel tube with a hole drilled through it. I then put the tube over the primer flash tube, pushed an m4 bolt through this hole and through the holes in the flash tube. It worked very well, and there was also no risk of damaging the outer tool slots.
