The Chiltern Society have written to the government in order to argue that HS2 works should not proceed during the Covid-19 pandemic.

The group claims the work should be halted because of the 'uncertain impacts on our national finances and future travelling habits' that the coronavirus outbreak has caused.

The society have penned a letter to Labour peer Lord Berkeley, part of which reads: "We are writing to you again regarding HS2, as there now seems to be a real possibility that Notice to Proceed may be issued during the current crisis, without proper examination of the revised business case and demonstration of management competence which should accompany this.

"Such a decision would be completely unjustifiable, given the uncertain impacts of this crisis on the national finances, and future travelling habits.

"The society has serious safety concerns regarding the Chiltern Tunnel. The original concerns – pollution of the Chiltern Aquifer, and the risk posed to the River Misbourne, still remain.

"To summarise, it is not clear that the Chiltern Tunnel can be constructed, or what environmental damage would result from its construction, or whether the completed tunnel could safely accommodate the frequency of services which have been used to justify the business case."
