Mark Wilson writes: Every home and business in the UK will have access to "fast broadband" by 2020. This is the latest pledge from Prime Minister David Cameron, who said access to the internet "should be a right." At the moment, 83% of homes and businesses in Britain have access to broadband connections 24Mbps and faster. By 2017, this is expected to rise to 95%. The latest plan is directed at the "last 5 percent" — such as people in remote areas — and will oblige broadband providers to supply at least 10Mbps broadband to anyone who demands it.
