CBI director-general Carolyn Fairbairn, pictured, said: “Some of our regions and nations have been left behind. There is a real gulf in opportunities between people in different parts of the UK. You might expect big gaps in productivity between regions, but productivity differences within regions are almost as big.
“For example, Solihull is a third more productive than Wolverhampton, just 20 miles away, where you’ll earn on average £5,000 less.
“Raising productivity across all parts of the UK should be the single most important domestic goal of the next five years.”
