The Ulster Unionist Party and the Conservatives have launched their joint manifesto for the general election.
The UCU, an electoral pact between the parties, is fielding candidates in all 18 Northern Ireland constituencies.
The parties back academic selection in secondary schools, reveal plans to make the province an economic enterprise zone and propose a ban on politicians sitting in both the NI Assembly and Westminster.
Shadow foreign secretary William Hague attended the manifesto launch.
"I am proud of the fact that because of the alliance between our two great parties we are the only political force putting up candidates in every part of the United Kingdom," Hague said.
"We are the one truly national, United Kingdom party standing in Northern Ireland at this election."
The UCU manifesto was described as "a profoundly optimistic ... authentically Conservative and Unionist vision: sound money, backing enterprise, trusting people".
They propose a change in the corporation tax rate in Northern Ireland to attract investment and said they are "unashamedly progressive".
"We want to end Northern Ireland's semi-detached political status and bring it back into the mainstream of United Kingdom politics.
"Each of the three programmes of reform outlined in this manifesto - our plans to build a new economic model; to build the Big Society; to build a political system where people have more power and control over their lives - is a massive undertaking in its own right.
"Yet we are proposing to carry out these changes all at once, because that is the only way to put the UK on the right path for a successful future.
"The UK faces huge problems that demand radical change; and it cannot come soon enough.
"We are impatient to get on with this work. We are determined to make a difference.
"We have the policies to make that difference. And most importantly, we have faith in the people of the UK, because we know that if we all pull together, stick together, then this country can change its future."
Manifesto highlights:
• Improve the United Kingdom's international rankings for tax competitiveness and business regulation.
• Back the NHS; support the plans of Conservative colleagues in England to increase health spending every year and will seek the same in Northern Ireland.
• Build on excellence in Northern Ireland's schools; commit to working with Ulster Unionist Assembly colleagues to establish a regulated, statutory process of post-primary transfer.
• Secure effective law and order for the entire community in Northern Ireland.
• Reduce UK greenhouse gas emissions and increase our share of global markets for low carbon technologies; promote small and large scale low carbon energy production, including nuclear, wind, clean coal and gas.
Hague said a Conservative government "will put Northern Ireland at the very heart of the Union".
