Prime Minister David Cameron says HS2 will create 100,000 jobs.
He added: “Linking communities and businesses across the country and shrinking the distances between our greatest cities, High Speed Rail is an engine for growth that will help to drive regional regeneration.
“We are in a global race and this Government’s decision to make High Speed Rail a reality is another example of the action we taking to equip Britain to compete and thrive in that race.
"High Speed Rail is a catalyst that will help to secure economic prosperity across Britain, rebalance our economy and support tens of thousands of jobs.”
The government has announced an extension to the controversial HS2 rail route.
The proposed route has angered people living in the Thames Valley as they are concerned about the impact on wildlife and property prices.
The extended route will now extend from Birmingham to Manchester and Leeds.
Deputy Prime Minister Nick Clegg said: "We have to move with the times as a country. We can't keep relying on Victorian infrastructure for 21st Century Britain.
"We can't keep turning a blind eye to the north-south divide in our economy. That is what this high-speed project is all about.
"Of course there'll be people who don't like one or other aspect of it but if we really want to build for the future, so that our children and grandchildren have a future fit for the 21st Century, we've got to get moving."
The Prime Minister is today expected to put High Speed 2 at the heart of the Government’s growth agenda and confirm the line will be extended to Leeds and Manchester.
It could spark anger in Oxfordshire and Buckinghamshire where the outcome of a legal challenge into the project is still to be made.
It's claimed the Government failed to properly consult on the scheme.
In a speech Mr Cameron will say HS2 is going ahead and will be the most important project in the UK to create jobs and boost the economy. He is attending a Cabinet meeting in the north where he is expected to make the comments.
Those opposed led by Buckinghamshire and Oxfordshire County Councils say the scheme will destroy large parts of The Chilterns.
It would link London and Birmingham and then go on to Leeds and Manchester. The cost is £32bn.
