A bank executive on Monday admitted killing his wife with a crowbar after she taunted him as “limp and useless” over his erectile dysfunction.

David Pomphret, 51, bludgeoned his 49-year-old wife, Ann Marie, to death, striking her 30 times over the head at the stables they owned.

Giving evidence in his trial yesterday, the computer expert at Barclays tearfully told how the row began when they had gone to pick up tools to fix their shower.

Described as a “quiet man”, Pomphret suffered abuse from his wife, who had depression, was being treated for cancer and had an autistic personality disorder, the jury has heard.
