What his plans are for future investment in London’s transport network.

As the Chancellor announced at the spending review, the Government are providing more than £5.8 billion in capital grant and a further £3.8 billion of borrowing power between 2015-16 and 2020-21 to Transport for London, which will enable it to continue to invest in critical transport infrastructure, including Crossrail and the tube upgrade programme. This is in addition to more than £10 billion that has been provided to TfL over the current spending review period up to 2015.

Can the Minister assure me that, in considering the case for Crossrail 2—which would link south-west London and north-east London—the Government will not forget that south-east London, the area I represent, barely makes it on to the tube map at the moment? Does he agree that the proposal to extend the Bakerloo line to Lewisham should form part of the strategic review of London’s future transport needs and how they can be met?

As the hon. Lady knows, the Government are making £2 million available to TfL for the Crossrail 2 study to take place. Any proposal to extend the underground is primarily a matter for the Mayor and TfL. To date, the Mayor has made no representations that suggest that the Bakerloo line extension is a priority for him.

Last week, a security scare closed the Dartford crossing and led to six-hour tailbacks along the M25 for local residents. Will the Minister explore ways of mitigating such problems in the future and helping the residents of Dartford, who are sick to the back teeth of problems arising from the Dartford crossing?

My hon. Friend is right about the significant repercussions for the residents of Dartford, but he will appreciate that security is our first priority. My right hon. Friend the Secretary of State has already called for an in-depth report into the incident, the implications, and what can be done to mitigate such effects in the future.

My hon. Friend Heidi Alexander is right to highlight the fact that south-east London is not served by the underground system and therefore is heavily reliant on the rail system. The plan to develop a road crossing at Silvertown, next to the Blackwall tunnel, will not sufficiently provide the extra river crossings and access to docklands that south-east London needs. I stress the need for extra public transport options—including, if we build the Silvertown link, a docklands light railway crossing—that will reduce the capacity on the roads.

I have listened carefully to the hon. Gentleman’s case, and I accept the point about the Silvertown link—indeed, the Mayor has made a commitment to look at that. As I said to Heidi Alexander, any proposal to extend the underground and the rail system in that part of London is primarily a decision for the Mayor.
