ON an earlier post I announced a demonstration against the visit of Colombia's new president Alvaro Uribe to London to get arms and cash off Blair and co. It is now not at Downing Street but at THE COLOMBIAN EMBASSY this Tuesday, 16 July from 5.30 p.m. on. This is because Uribe will be holding a press conference there at 6 o'clock. The Embassy is at 3 Hans Crescent, Knightsbridge, London, round the back of Harrods.
