One of the most common arguments used by Unionists against Welsh independence is that Wales cannot afford to pay its own way. They repeat that Wales receives £18bn a year as a ‘handout’ from the UK, and cannot survive without this ‘subsidy’. They overlook that Wales also generates taxes and revenue, collected directly by the UK, and the £18bn is largely a return of that.

However, it’s been difficult to refute such claims as there was long a shortage of reliable data on the economic performance of Wales. There’s a huge body of economic statistics and data published by the UK Government in its National Accounts – commonly referred to as ‘The Blue Book’ – but it’s difficult for the average person to follow, let alone extract the necessary data in a Welsh context.
