made any donations to the Conservatives before his delusions began to take hold in 1984, and the pattern of giving which began thereafter cannot in my judgment be dismissed as no more than a reflection of his long-standing support for the party and his admiration for Mrs Thatcher. 225. The surviving letters which he sent to Mrs Thatcher, David Mellor and others make it clear, in my view, that there was a definite connection between Bane’s deluded beliefs and his relationship with the Conservative Party. Bane no doubt continued to espouse conventional Conservative values as he had before his illness, but with the difference that he now saw them as having a particular virtue in helping to defend the world, and himself, against the conspiracy of dark forces. The link is made clear as early as Bane’s first letter to Mrs Thatcher in December 1984, when he sent a cheque for £5,000 “to fight the evil wicked Demons - SATANS and I am fully on your disposal”. A similar attitude can be seen three years later, in his letter of 13 December 1987 to David Mellor, where he refers to his nomadic existence and the dark forces conspiracy, asks Mr Mellor to be his trustee and to recommend a trustworthy solicitor, and says how important it is for him that his substantial wealth should not finish “in the hands of destructive people – Satanic Monsters”. The same letter then goes on to reaffirm, in extravagant language, Bane’s attachment to this country and his admiration for Mrs Thatcher: “Our Prime Minister is the greatest Leader of the Free World in the human [peacetime] history … God knows when we shall have again such a unique and genius person”. The importance of these letters, and others like them, is that they make explicit the link in Bane’s mind between his delusions and his support for the Conservative Party and its values. In the light of this link, and the expert evidence on the fixed nature of untreated delusions, I find it impossible to attach much, if any, weight to other letters which, read in isolation, appear to endorse traditional Conservative values and do not refer to the dark forces. An example of such a letter is Bane’s letter of 18 April 1987 to the Right Hon. Norman Tebbit MP at Conservative Central Office enclosing a donation of £3,000 for the next general election, saying, “Our Maggie is not only our dear PM – she is really today the Leader of the Free World and we must support her unconditionally to enable her Vision and Charisma to save and protect our dignity, decency, democracy and freedom.” 226. A similar point may be made in relation to Bane’s instructions to Mr Trower, and the preparation of the 1988 and 1989 Wills. To judge from Mr Trower’s attendance note, Bane’s original instructions to him at their first meeting were on the face of it entirely rational. However, Mr Trower can have been in no doubt that Bane suffered from some form of mental illness once he saw some of the letters enclosed with Bane’s letter to him of 16 June 1988; and some of Bane’s subsequent letters to Mr Trower, including in particular his letter of 19 December 1988, can only be described as totally deranged. Mr Trower’s reaction to these letters seems to have been one of embarrassed silence. There is no indication that he advised Bane to seek psychiatric help, nor did he suggest that the 1988 and 1989 Wills should be witnessed and approved by a medical practitioner who had satisfied himself as to Bane’s capacity and understanding and made a record of his examination and findings (the so-called “golden rule” referred to by the Court of Appeal in Sharp v Adam at paragraph [27]). My strong impression is that Mr Trower turned a blind eye to the problem, and
