[Treasury chief George Osborne] will also announce an extra £30 billion in new money to be spent on infrastructure such as railways, roads, classrooms and broadband connections, said a person familiar with the matter. Of this, £20 billion will be provided by pension funds. The Treasury has signed a memorandum of understanding with the National Association of Pension Funds to provide this cash. Another £5 billion will come out of savings in other government departments and be spent over the next four years. The other £5 billion will be spent after 2015, but plans will be set out now.
