The controversial project to build a new high speed rail line through parts of Buckinghamshire and Oxfordshire will get the final go-ahead next week in the Queen's Speech, ITV News Meridian can reveal.
High Speed 2 (HS2) will be one if the top priorities for Government legislation over the next year.
Full details will be revealed next Wednesday.
In effect it will allow the company set up by the Government to build the line to press ahead with the project and will start its process of Parliamentary approval later this year.
The line will be built from London to Birmingham and later extended to Manchester and Leeds as part of phase 2.
It will pass through much of Buckinghamshire and Oxfordshire near to Wendover, Aylesbury, Bicester and north of Banbury.
The cost of the new line is £33bn.
Critics say the line will destroy countryside in the region and has no business case.
HS2 say it will create thousands of jobs be a major boost to the economy.
