Hunt urged to invest £30bn a year in infrastructure or risk ‘decade in doldrums’

Thinktank says stronger than expected tax revenues have given chancellor scope for bold package in autumn statement

Jeremy Hunt risks condemning Britain to a decade in the doldrums unless he uses this month's autumn statement to announce a 30bn-a-year investment plan to upgrade public infrastructure, a leading thinktank has warned.

The National Institute for Economic and Social Research (NIESR) said the chancellor should ignore calls by Tory MPs for pre-election tax cuts and instead focus on measures to boost growth through improvements to transport, digital networks, skills and housing.
