Boris Johnson's £640m vision for London cycling

The Mayor of London wants to invest an additional £640m in cycling in the capital over the next ten years.

The funds would be in addition to the £273m already in Transport for London's (TfL) 10-year base plan.

The money would be spent on improvements including new cycling routes, more cycle hire and safer road junctions.

But delivering them will depend on gaining funds from the government.

The TfL business plan is due to published on Tuesday.
