She offered assurances that Whirlpool's actions are kept under review and added: "I can tell the House we have informed Whirlpool of our intention to serve a recall notice as a next step of the regulatory process. "This is unprecedented action." Following previous reports of the design fault, Whirlpool began a drive to modify affected dryers, with millions of those under its Hotpoint, Indesit, Creda, Swan and Proline brands identified as requiring a fix to make them safe to operate. But dozens of people whose dryers were apparently fixed have since reported fires or a strong smoke smell. A Whirlpool spokesperson told Mirror Online : "Safety is our number one priority and we remain committed to resolving any affected tumble dryers that have not yet been modified. "To this end, we are in ongoing discussions with the Office for Product Safety and Standards to agree additional measures we have proposed to reach consumers who have not yet engaged with this safety programme.
