Dame Helen Mirren was on hand to help honour volunteer life-savers at a ceremony in London over the weekend (08-09Jun13).

Mirren's pal, publicity chief Chris Worwood, suffered a cardiac arrest at a red carpet screening of her movie The Debt in 2011, but he was saved by quick-thinking police officers who were able to resuscitate him.

The Queen star subsequently became patron of the London Ambulance Service's charity, the Voluntary Responder Group, and she turned out to honour other lifesavers at the organisation's awards ceremony in the British capital on Sunday night (09Jun13).

During the event at London's City Hall, Mirren spoke about her friend's recovery and insisted more lifesaving defibrillator machines should be made available to the public.

She said, "Chris is alive because he was given Cpr (cardiopulmonary resuscitation) techniques and and shocked by a defibrillator. More of these life-saving machines should be available across London to give others a chance of survival."

She added, "It was an honour to be in the presence of people who give their time to save the lives of others."

The award winners were presented with glass trophies and asked to chose a location for the installment of public-access defibrillators.
