Six councils in Northern Ireland are pitching to the government in a bid which could lead to the creation of 20,000 jobs over 10 years.
Belfast City Council has partnered with Antrim and Newtownabbey, Ards and North Down, Lisburn and Castlereagh, Mid and East Antrim, and Newry, Mourne and Down, universities and higher education institutions.
They hope to secure £1bn as part of a city deal. The £450m from the Treasury will be matched by the executive.
The proposed deal, which has been submitted to Northern Ireland Secretary of State Karen Bradley, focuses on four key areas of investment – digital and innovation, infrastructure, tourism-led regeneration and skills and employability.
City deals are packages of funding and decision making powers which allow councils to boost the economy through large projects.
Funding will come from the Treasury, the executive and councils.
Chancellor Philip Hammond will announce if the investment will get the go-ahead and how much the government will provide in the autumn budget.
