Nothing of evidential value just the drip, drip of poison. Eg the police asked JB if he had a good relationship with his father to which he replied yes. AE then told the police this was not true. Whereas we are told by CC in his wit stat that JB had a good relationship with NB which he expanded on by giving examples.
He did have a good relationship with Nevill. A lot more than either shelia or June. They were close at times and Nevill thought highly of him as well. Inez brown saying " Jeremy was nevills favourite"
Bambers strained relationship with June put Nevill in the uncompromising position between batting between his wife and adopted child. However I never have seen adoption as a major major issue and both children were adopted by Nevill and June from babies.
