Boris Johnson’s infrastructure speech didn’t so much deliver revelations as reminders. There were no great new announcements. Instead there was a series of rehashed promises from the 2019 general election campaign. The government would build 40 new hospitals, improve school infrastructure, speed up HS2, reform the planning process, and invest in scientific development, Johnson said. This might be regarded as a surprisingly radical list for a Conservative prime minister to deliver, had he not delivered it countless times before on the stump.
