Experts sound alarm over PM's pledge to 'level up' UK economy

Boris Johnson would need two full terms as PM to fulfil election vow, says thinktank

It would take Boris Johnson two full terms as prime minister to fulfil his pledge to "level up" the British economy, according to one of the UK's leading economic thinktanks.

The National Institute of Economic and Social Research (NIESR) said Johnson's plans would probably take more than a decade to raise the level of economic output across the country, due to capacity constraints.
