Ms O’Meara, who will formally announce her decision to stand today, will campaign for a new proclamation for Ireland to be declared in 2016.
“The first Proclamation was ambitious and inspiring, but there are many ways we did not live up to it,” she said.
“We did not cherish all the children of the nation equally, for instance, and still don’t. And we have had to concede sovereignty in the face of a financial failure, in order to survive and continue to exist.”
The former RTÉ journalist served in the Seanad for 10 years, ran for the Dáil in Tipperary North and is currently head of advocacy and communications at the Irish Cancer Society.
“As a journalist, politician and now cancer advocate, I have brought and continue to bring my passion for leadership and social justice to my work,” she said.
The Nenagh native added that she wants to “contribute my talents and skills to the rebuilding of this nation” .
The theme of her presidency would be “Rebuilding a Nation.”
In a statement last night she said: “Amidst the wreckage we are now in is an opportunity to start again, to preserve the best of what we have created and build a new vision to take this nation forward.”
