The announcement of small business grants for high speed broadband coincides with the Small Business Saturday initiative promoting the firms Mr Cameron described as the "lifeblood of our economy".

To do that we are working on a complete overhaul of the UK's infrastructure; high speed broadband is a vital part of this. And on Small Business Saturday, what better way to support small businesses - the lifeblood of our economy - than to help kit them out for the 21st century.
