The two parties have worked together over the last two coalitions.
A Laois Fianna Fail TD believes his party and Fine Gael should avoid merging at all costs.
Sean Fleming says it's "lazy journalism" that's leading to talk of the two parties joining.
Fianna Fail and Fine Gael have been opposed since the Civil War in the early 1900s, but have found themselves in government together over the course of the last two coalitions.
Deputy Fleming says they're working together well but that shouldn't lead to a merger:
