Minister for Finance Michael Noonan has said his current ministry is the "best job he's ever had".

He said once the Government got over the difficulties at the start, it was very interesting and fruitful.

Mr Noonan, who will not continue as a minister after the expected election of Leo Varadkar as taoiseach on Wednesday, said he believes he is leaving the job with the country in good shape.

He said among the highlights of his time in Finance was phoning Taoiseach Enda Kenny to tell him the Troika was leaving Ireland, without any conditions.

"He was touring Donegal at the time and he still talks about pulling the car off the road and that being the start of a great 48 hours.

"The Irish people first of all didn't think it would happen so soon and there was a real celebration that we got our sovereignty back."

Asked about Brexit, Mr Noonan said Ireland is well prepared for Brexit but would be better prepared if we knew what the British plan is.

Mr Noonan said he accepts there is pressure to provide extra infrastructure and he fully agrees with that. 

However he said he does not think the Government will have to make a choice between investment in additional infrastructure and the prospect of a rainy day fund.

He said the economy is growing fast enough and there are sufficient resources to do both.

Mr Noonan was asked what advice he would give the next minister for finance.

"I think they will follow the lines of policies that have been set out already. I think internationally sudden departures from policy wouldn't be helpful but the incoming Government has to comply with the programme for government because that's the agreement with Fianna Fáil," Mr Noonan stated.

He said he hopes progress will continue and next year, and the year after, there will be extra money for gardaí, health and education and for the capital investments so badly needed such as extra schools, health centres, better roads and broadband.
