More than 2 million workers have begun saving into a workplace pensions scheme as a result of automatic enrolment, according to figures released today by The Pensions Regulator.
Automatic enrolment began in October 2012, when supermarkets and other large employers led the way.
Eventually 9 million people will be signed up - though they can opt out if they want to.
3,500 employers have joined so far but tens of thousands more will start signing up staff next year as medium-sized companies get involved.
All employers, including charities and the public sector, will have to enrol eligible workers into a pension scheme.
