evidence: On top of existing spending, taxpayers across the UK will have to fork out an extra £400m for infrastructure in Northern Ireland, £350m more for health and education, another £150m for better broadband and £100m to tackle deprivation. [...] A further £500m could also be available to Northern Ireland as the UK Government agreed to loosen spending rules constraining existing money already committed to Belfast. Former permanent secretary to the Treasury Nick Macpherson branded it "profligacy", adding on Twitter: "£1bn for Ulster is just a downpayment. DUP will be back for more...again and again... They have previous in such matters."
