ENGLAND has "had nothing from devolution," Boris Johnson has complained, insisting it is the great cities of England, which are the motors of the UK economy.

In an interview with Total Politics magazine that ranged from HS2 to Ukip and from translating Latin to sexual intercourse, the London mayor again refused to rule out becoming an MP or denied wanting to be Prime Minister.

Asked if Scotland voted Yes to independence, it would be inevitable that more powers would have to be devolved to London and other cities, he replied: "Absolutely, I really believe it. England has had nothing from devolution.

"The great English cities are motors of the UK economy, they hold the keys to the future success of the UK and it would be a stunning thing to galvanise those cities and get them onto really targeted policies."

In the interview, Mr Johnson: claimed that house prices were what protesters were really worried about, said the UK was living in "cloud cuckoo land" on immigration because of the EU's free movement rule and called for an end to "completely untrammelled" immigration from Europe, argued for an amnesty for illegal immigrants who had been in the UK for more than 10 years.

He also colourfully suggested London was successful because people were having "more sexual intercourse", declared winning back urban Britain was the "future of the Tory Party", demanded his party campaigned as the "party of the Living Wage" and claimed voters do not know what Ed Miliband stands for, saying: "He's neither fish, flesh nor fowl."
