evidence: "Northern Ireland has lost out as the result of a deeply unbalanced economy within the UK. There is a heavy focus around the south-east of England and those sectors which predominate there. For example, only 3/12 UK regions are net contributors to UK Treasury." [...] In other words, if a region is receiving more from UK Treasury, in terms of revenue to a region’s residents and businesses, than revenue that the region gives to UK Treasury (e.g. via taxes), then that region is said to have a "positive net fiscal balance". Conversely, a "negative net fiscal balance" means that a region gives more revenue to UK Treasury than the revenue that the region receives from UK Treasury. The Alliance Party stated in their Westminster Manifesto 2019 that "only 3/12 UK regions are net contributors to UK Treasury". Data from the ONS corroborates this; only London, the southeast, and the east of England are net contributors to the UK Treasury. The claim by the Alliance Party is accurate.
