Basil McCrea and John McCallister have launched their new political party at The Mac in Belfast.
Called NI21, the new party was formed after the two UUP rebels resigned in February over a decision to field a joint by-election candidate with the DUP.
There was much speculation abut the name of the the new party this week after Mr McCrea registered the 'NI21' name as a website.
The party confirmed that it refers to the 21st Century, saying: "We believe it is time for a confident, generous and progressive pro-UK party to step forward and build support for a modern Northern Ireland in the 21st Century.
"In choosing our name, we aim to build on the Northern Ireland identity and offer voters, as well as those disengaged in the political process, an opportunity to support a new party – a party not tied to the baggage of the 20th century, legacy and conflict.
"In the post Good Friday Agreement Northern Ireland we believe every citizen has a valuable role to play in our society regardless of their religion, age, gender, sexuality or ability."
A statement on Basil McCrea's website said NI21 would seek to move the political debate beyond the "sterile politics of the past".
He pledged: "It will not duck the difficult issues, nor sit on the fence.
"It will provide genuine leadership, a stern challenge to the status quo and a viable democratic alternative to the current incumbents."
The launch takes place from 7.15pm on Thursday, June 6, with a huge emphasis on using digital and social media to engage with the public.
Who else is in the party?
NI21 says it had over 170 guests at the party's pre-launch in the Malone Lodge Hotel last month - and over 500 phone, email, text and personal enquiries to attend or participate in future events.
But who has been recruited to front NI21 alongside Basil and John?
Six members have been named, of which five are women and three are 30 or younger.

NI21 explains why a new political party is needed in Northern Ireland.
Differences between NI21 and Alliance
"One of the main differences between ourselves and the Alliance party is Alliance have sought to hitch a ride on the Sinn Fein / DUP Juggernaut at Stormont, content to be part of an Executive which has failed to live up to expectations.
"Our party will offer a robust and constructive opposition, standing up for struggling families and hard pressed businesses in Northern Ireland.
"As we develop detailed policies over the summer, we will show how as a party the citizens of Northern Ireland can robustly participate in politics while still able to celebrate and cherish their own individual heritage.
"Our party has been established to show Northern Ireland people are a diverse people, people who are capable of understanding we are all different and as such, that should be celebrated and embraced."
"The decision to run a Unionist Unity candidate in the Mid Ulster by-election did little to improve the political situation in Northern Ireland
"It further polarised our communities, with the potential to increase tension and reinforce the political domination of the DUP and SF.
"This political monopoly by the big two has not served Northern Ireland well. Self-serving, unproductive and ultimately unsustainable, their time in office has been a failure."
The Constitutional Question
"Our party supports unequivocally the 1998 Good Friday Agreement which settled the Constitutional Question that Northern Ireland remain as part of the United Kingdom so long as the majority of voters so wish.
"There is no prospect of a border poll in this election cycle or for the foreseeable future."
"We are a party which supports Northern Ireland remaining in the UK. We have said repeatedly that as we are required to designate as ‘Unionist’, ‘Nationalist’ or ‘Other’ in the Assembly, as a pro-UK party we will designate as Unionist.
"However, we also feel there is a debate to be had about the designation issue and our party will bring forward proposals in the coming months, along with a Private Members Bill for Opposition."
"To many families in our community, the word ‘Unionist’ has negative connotations. Not everyone who supports Northern Ireland remaining part of the UK can easily associate with the main Unionist parties or all that is associated with Unionist culture.
"Our party brings a fresh approach to politics in Northern Ireland, allowing people to celebrate their diversity and culture, celebrate their Irish or British heritage while comfortably remaining committed to Northern Ireland remaining part of the United Kingdom."
Why a New Party?
"Democracy itself needs a choice, and Northern Ireland needs a new political dynamic. For those reasons and for the many people who despair of the political landscape in a place we like to call home, we have concluded that a new political party is required.
"NI21's guiding principles are:
- A Northern Ireland party determined to represent all sections of our community.
- A party that is not afraid to speak out.
- A party capable of building a Northern Ireland we can all be proud of.
- An independent party which believes that Northern Ireland’s future is best advanced within the Union
- A party committed to the values enshrined in the Belfast agreement and determined to provide a credible alternative to the current political stalemate
- A party that does not need to wrap itself in a flag, to provide leadership to the people of Northern Ireland.
- A party which believes in individuals as agents of change, where religious persuasion should not define political beliefs and where matters of conscience are best left to the individual.
"Back in 1998, there was a sense of optimism in Northern Ireland. An historic international agreement had been reached on the way forward in our divided society. Whatever the logic for those divisions in the past, there is none today.
"We have accepted the challenge to build a new party but we cannot do it on our own.
"The unpalatable truth is that politics is too important to be left to the politicians. If the electorate wants better politics they will have to become more engaged in the political process.
"An informed and interested electorate is essential for democracy to prevail and Northern Ireland to prosper."
