In the same speech, the Prime Minister promised to increase NHS spending, GP appointments and nurses, introduce Australian style points-based immigration system and increase policing levels by 20,000.
He also pledged to implement “colossal new investments in infrastructure and science, using our technological advantages to make this country the cleanest, greenest on earth, with the most far-reaching environmental programme.”
He added: “And you the people of this country voted to be carbon-neutral in this election – you voted to be carbon-neutral by 2050. And we’ll do it.”
