Update...

I have at last raked this bed to a fine tilth.

I have also dug the rest of this besd over but it will need some weeding at the raspberry end - convolvulus & couch grass:(

I have however cut down the raspberry plants in readiness for - deep breath - removing the ground cover.

I weeded and dug the seedbed frame in order to have some space for seed sowing. I might put a bag or two of manure and some topsoil in first, though...
