David Cameron has launched the first ever English manifesto stating it will bring success to every area of England.

The prime minister outlined the benefits of having "one document in black and white" clarifying to English voters "what they can expect in the future", after saying it was "vital" English MPs voted for English laws, which would strengthen the UK rather than fragment it.

Speaking in Lincoln, alongside William Hague, he listed future transport improvements the country could look forward to, including the upgrades to the M6 and M62 in the north-west and the continuation of the £14.8bn ($22.3bn) Crossrail project in the south before pledging greater investment in green energies in the north.

He said: "These plans are not all one size fits all. They are tailor-made for each part of England. In the east backing for industries, like off shore energy and agritech. In Yorkshire, a focus on advance manufacturing and financial services. In the south east easing congestion by improving transport links in and out of London.

"There's £4.5bn in transport investment in the north-east. More enterprise zones in the West Midlands. In London there is Crossrail to be finished and in the south west A303 to be dualled. In the East Midlands there would be over 270,000 apprenticeships to be created, plus an extra 135,000 more people in work in this area since he became Prime Minister five years ago.

He added: "This is about every part of England sharing in our success."

His speech comes as he said it was "vital" English Mps have the final say over income tax as the current system was "unfair" and acted as a "real threat" while more powers were devolved to Scotland.

"Soon, the Scottish Parliament will be voting to set its own levels of income tax - and rightly so - but that has clear implications," he said.

"English MPs will be unable to vote on the income tax paid by people in Aberdeen and Edinburgh while Scottish MPs are able to vote on the tax you pay in Birmingham or Canterbury or Leeds.

"It is simply unfair. And with English votes for English laws we will put it right."

"English votes for English laws is not about fragmenting the UK," he added. "It's not about division and difference and pulling apart, it is about making our United Kingdom stronger.
