Open letter to Tony Blair: Call to prevent escalating violence

An editorial error occurred in this open letter to Tony Blair (p 220, 25 January). By adding “the” to the authorship line we implied that the letter had been signed by all staff, students, and alumni of the London School of Hygiene and Tropical Medicine. The authorship line should have read: “On behalf of 500 staff, students, and alumni of the London School of Hygiene and Tropical Medicine, and in collaboration with Medact” [not “On behalf of the staff, students, and alumni . . .” as published].
