"We know what good looks like - we need to get on and build it."
A government spokesman said: "At the Spending Round we set out £100 billion of what the report highlights as 'bold ambitions and flagship projects which if delivered will provide a significant boost to UK competitiveness'.
"The Government's focus is now on implementing these plans."
