The proposed HS1-HS2 link was subject to some criticism and concerns were raised by Camden London Borough Council about the impact on housing, Camden Market and other local businesses from construction work of the link. Sir David Higgins, chairman of HS2 Ltd, recommended that the Camden railway link should be omitted from the parliamentary bill, stating that HS2 passengers from the North of England would easily be able to transfer from the HS2 terminal at Euston to St Pancras by London Underground, to continue their journey on HS1 to continental Europe. He also recommended that alternative plans should be drawn up to link the high-speed lines. At the second reading of the High Speed Rail Bill in April 2014, the link was omitted from the final proposals. Following this decision, London mayor Boris Johnson expressed the opinion that an HS1-HS2 link should instead be provided by boring a tunnel under Camden.
