High Speed 2 Compensation

I have a constituent called Siân Froggatt, and she had a compulsory purchase order made against part of her farm, involving land that is the only way she can access her farm. Three times she has petitioned HS2 to buy it back, but it says no, and the land will now go on to the open market. How can that be right—I hope the Minister will address this—when the railway line will not even be going alongside? She is willing to pay back the money for her land that was compulsorily taken off her.
