Sir – A recent walk in fields near Little Clanfield was made nearly impossible by crops of rape, which had spread at chest height across the paths.

I understand similar obstruction also occurs in other places in Oxfordshire and has affected me in previous years.

Unfortunately the county council’s countryside services section seem incapable of developing a strategy which will make farmers regularly inspect paths on their land to ensure that unimpeded access along rights of way is maintained as is required by law. I have written to the county council but am not optimistic that any effective action will be taken.
