West Dorset MP Chris Loder has told MPs how one of his parliamentary assistants carried out CPR on a victim of the Forbury Gardens attack.
He told the commons:"In the same way that (Tobias Ellwood) did so in March 2017, another member of our parliamentary family who, by chance was at Forbury Gardens on Saturday, ran courageously towards danger, his only focus to help the injured."
Mr Loder said his staff member James Antell "not only used his own shirt to stem the bleeding of one victim, but continued resuscitation on a second victim until the paramedics arrived".
He added he was "extremely proud" of his assistant's "remarkable and extraordinary effort".
In response Home Secretary Priti Patel said: "Responding, Home Secretary Priti Patel said: "Can I join with (Mr Loder) a tribute to his assistant and to all other first responders who showed great humility but also that sense of duty in coming together on Saturday in Forbury Gardens to respond and prevent the further loss of life."
