Rachel Reeves expected to review pensions auto-enrolment

Exclusive: Announcement expected as part of series of changes outlined in chancellor's Mansion House speech

The chancellor, Rachel Reeves, is expected to trigger a review of the auto-enrolment pension scheme next week in a move that could ultimately force employers to raise their contributions to staff retirement pots.

The announcement could come as early as Monday, forming a key part of the Labour government's pensions review, industry sources told the Guardian.
