The Fianna Fáil leader says a second budget may be needed to provide the resources to combat the coronavirus.
Micheál Martin said a stable government needs to be in place in order to make the big decisions around Covid-19.
Talks between Fine Gael and Fianna Fáil aimed at forming a government are due to resume on Wednesday.
Micheál Martin says a new government is needed to make the big decisions.
"The decisions that will be taken will be quite fundamental in character.
"They do demand a government I believe that has the certainty of a mojority and also the certainty of time to take them and to deal with the consequences of covid-19."
