Business leaders are urging the government to put more resources towards improving the UK's digital infrastructure.
The British Chambers of Commerce (BCC) has identified broadband as a particular area of concern, as the 24Mbps speed that the government defines as superfast is far behind the expected 30Mbps or above in many other European countries.
As a result, it believes the government must offer funding equivalent to the rollout of superfast broadband to extend ultrafast broadband coverage across the UK.
John Longworth, Director General of the BCC, commented: "The digital world is changing daily and UK firms have a track record as global innovators and leaders. However, the infrastructure they rely upon is failing to keep pace."
Mr Longworth pointed out that while Britain is a world leader in areas such as ecommerce, many business parks, offices and rail routes do not have adequate mobile and broadband connectivity.
He therefore believes the bar must be set much higher to ensure that UK businesses remain competitive in a global marketplace.
"The UK government must set a far more ambitious digital strategy, starting with an immediate action plan to boost mobile and fibre connections for business," Mr Longworth said.
He went on to point out that connectivity problems are being reported among companies of all sizes, in every industry and region of the UK.
This, he said, means ministers, regulators, service providers and businesses themselves must all take action if Britain is to "stay competitive in future".
The BCC has presented its argument in a letter signed by all 52 accredited chambers across the UK and handed it to Culture Secretary John Whittingdale.
