The locking/unlocking on the move sounds like the car is trying to do what it should but thinks a door is open, that's why it won't stay locked.
Might be worth starting your investigation at the boot since it has its own fault. There's a release on the inside if you fold down the seats and wriggle through.
Full details in your handbook.
When I had central locking problems on an older car, it turned out to be broken wires in the wiring connection at a door. Years of opening and closing eventually takes it's toll.
Try this, fruitsalad. ( your keyfob may also need a new battery ).

I found a sequence on the Citroen Owner’s Club Website, thanks to Andy which tells you to:

Put the driver’s window down, lift the bonnet and ensure all equipment is switched off.
Ensure all doors are closed and remove key from the ignition.
Wait for 3 minutes, disconnect the vehicle battery and wait 15 seconds.
Reconnect the vehicle battery, wait a further 10 seconds (do not open doors.)
Switch on the side lights through the driver’s window.
Switch on the ignition and check system’s functionality.
Hold lock button on key down for 10 seconds.
Remove key open & close door test central locking system
Start the engine and complete the system’s check.
I went through this sequence, and lo-and-behold, the central locking works again.
It might be the magic answer, or Tony might be sniggering.
