A BRILLIANT schoolboy shot himself in the head after carefully calculating the benefits of life and deciding it was not worth living, an inquest was told yesterday.

Dario Iacoponi, 15, a pupil at the London Oratory in Fulham, west London, which is attended by Tony Blair's two sons, Euan, 14, and Nicky, 12, kept a diary of his philosophical thoughts on life in the two months leading up to his death. The Oratory is one of the top Roman Catholic schools in the country.

After weighing up the pros and cons, he decided to commit suicide and planned it meticulously. He taught himself to use his father's shotgun and worked out how to fire it with a wooden spoon. He then waited until neither of his parents was at home before carrying out the plan last month.
