Fianna Fáil leader Micheál Martin has said the Taoiseach should speak to him about the confidence and supply deal and not just speak to reporters about it.
Mr Martin said it was basic courtesy. He said over the last six months he had been looking at leaks and commentary in the media about renewing the deal.
Micheál Martin said the Taoiseach was behaving like he had a divine right to power.
However, he said he was happy with the current agreement, which ends after the upcoming Budget, when a review will take place.
Mr Martin said he was not giving a blank cheque before the Budget.
Earlier, Taoiseach Leo Varadkar said it would be prudent to renew the confidence and supply agreement with Fianna Fáil before it expired.
He said that for a Government to function, govern well and look after people's interests, it needed to know that it would be around in a few months’ time.
Mr Varadkar said he wanted to renew the confidence and supply agreement because, while the Government was working well, it would need an extension to address a lot of work dealing with outstanding challenges.
However, he said that was something he should discuss with Mr Martin before discussing it with the media or the wider public.
