Micheal Martin says he'll be in RTÉ on Tuesday night for a TV debate on the referendum, but doesn't know if Enda Kenny will show up.
The Taoiseach has been ignoring invitations to appear in TV debates in the run-up to next Friday's vote.
And Micheál Martin says if Gerry Adams wants to fill in, he's happy to debate him:
"I'd love to debate with Gerry Adams - I've already said that - in fact, I'd like to talk to Gerry about what he said in the Dáil only last July when he said that this was a pogrom - a democratic coup, but a coup nonetheless," he said.
"And he said this was going to give the government more power and was going to give less say to elected politicians and to the people – so yes, I'd certainly like to have that debate with Gerry."
