My hon. Friend is right that we need to continue extending the infrastructure of tube lines in London. We made it clear in the autumn statement that funds for the Jubilee line are reserved. My hon. Friend will appreciate that it is a matter for negotiation between the two parties to the partnership—the Government and the creditors of the former Olympia and York. Those discussions are proceeding. I hope that we shall be able to start construction in the near future, subject to those discussions.
