Can anyone help my neighbour. I am a great fan of growing green manure and I use a mix of Red Clover & Yellow Mustard. I will be sowing in the next couple of weeks for digging in next spring. My neighbour would like to sow some as well but he unfortunately has club root in his ground . He read somewhere that there is a green manure that you can sow now and leave for two years and this can fix the club root but he cannot remember what it was. Can anyone help ?

Thanks I had a feeling that might be the case.
He wants to let it rest next year anyway so I will pass this on

There is nothing that will eliminate club root in that way as it is a persistent fungus (slime mold or plasmodium) and the spores last in the ground for years.
The only way to get rid of it is to allow nothing in the brassica family to grow on the land for at least seven years (rather difficult when so many weeds are brassicas) and then you might be ok.
Using very powerful fungicides might help but then you will poison the ground and maybe yourself.
The real answer is to try to buy club root resistant varieties and in any case to grow the plants in large pots, only planting them out when they have established a large root ball. That should enable you to succeed with some brassicas though not things like cauliflowers.
