If any evidence regarding MM is deemed unobtainable due to an “illegal search” I believe the BKA will hand over all their evidence to the Met and see what a jury at the Old Bailey make of it . Personally speaking I’d scrap the recent trial appeal and put it all together in the MM case.Only right and proper but if that final piece of evidence is either unobtainable or doesn't point to CB then at some stage it'll have to be dropped, since 2017 he's been investigated I'd venture they're at the stage I've mentioned.
