WENT TO THE CAR THIS MORNING WOULD NOT START, ONLY TURNED OVER SLIGHTLY,
CALLED THE BREAKDOWN GUYS OUT , THEY SAID BATTERY FULLY CHARGED, PUT HIS BATTERY PACK ON ,STILL NO JOY !
HE TRIED 24V STILL NO JOY, HE THINKS SOMETHING HAS SLOWLY SIEZED IN THE ENGINE , DROPPED A VALVE ?????

IS THIS THE END, IF IT NEEDS NEW ENGINE THE CAR IS SCRAP !!!!

To eliminate a dropped valve or major engine problem such as seizure, turn the engine by hand using a spanner or socket and bar (ratchet) on the crank pulley....it will be easier with the glow plugs removed.
If the engine turns normally then look elsewhere.
First thing I would check after making sure the engine turns without issue is the earth wire to the starter, then remove the starter and have it tested.

I had the same issue. It turned out to be the starter motor.

Like you it turned over slowly so i suspected the battery at first. But that was not the problem.

My previous starter motor lasted for 2 years (~ 80 k miles)

If its a reduction gear gear type starter which I think most of them are when the grease in the motor gearbox dries up it will cause slow rotation, a little gear oil in there usually speeds it up.
