The campaign is to launch within the next two months and is being handled by PR agency Glasgows Group.

‘What is important about the internet to one person may not matter to another. But the internet has to be important to local businesses if it offers them a way to expand their markets,’ she said.
She added that the campaign has been prompted by the assembly’s concern that Wales should not fall behind the rest of the UK.
