The minister in charge of HS2 has said he is "concerned" at the rate of increases in actual and potential costs for the high-speed railway project.
Andrew Stephenson expressed his unease as he told Parliament that HS2 Ltd drew on an extra £500m of its £5.6bn contingency funds between September 2021 and January 2022.
He said the Government-owned company is also reporting a £400m increase in "potential cost pressures" - from £1.3bn to £1.7bn.
