Energy and transport to get share of £100bn

Plans for a £100bn modernisation of the UK's infrastructure, including new homes, road repairs and improved flood protection, have been announced.

The package, of which £50bn will come in 2015-16, is also aimed at boosting new sources of energy like shale gas.

Treasury Minister Danny Alexander said the plans put "long-term priorities before short-term political pressures".

But Labour said projects must start now and capital investment in the engine of the economy was actually falling.

The announcement of the government's infrastructure plans came a day after Wednesday's Spending Review, in which £11.5bn of cuts to Whitehall departments were spelt out.

While the first £50bn is committed to infrastructure projects starting in 2015-16, the rest is for the period from 2016 to 2020.

The main funding commitments include:

• £3bn to build 165,000 new affordable homes
• £28bn for road improvements, including £10bn for essential maintenance
• £10bn to clear a "backlog" of school building repairs
• 850 miles of railway to be electrified as part of £30bn rail investment
• £250m for extended super-fast broadband to rural areas
• £370m for flood defences. Agreement with industry to provide affordable insurance for flood-hit homes
• £800m extra funding for Green Investment Bank
• £150m for health research including into dementia
• £100m for a new prison in Wales
