The Finance Minister has confirmed that he believes aliens do exist on other planets.

Paschal Donohoe is the latest political figure to take part in Sean Moncrieff’s “Quick-Fire Quiz” on Newstalk.

Before taking on the three-minute quiz, this afternoon, the Dublin Central TD told Sean that he has no interest in running for leadership of Fine Gael.

When the timer got going, he revealed that his little toe is his least favourite body part, he loves a bit of Eurovision and “definitely” believes that aliens exist on other planets.

He also confirmed that very few people recognise him when he sticks on a pair of shorts and that Richard Boyd Barrett is a politician he likes but disagrees with.

On a more serious note, he confirmed that he has witnessed sexism in the Dáil.

Asked if he said anything about it, he said: “It was quite a while ago and in some conversations afterwards I made the point about it.”

After the egg-timer, he answered questions from the children at O’Connell’s National School in Dublin City Centre.

Why don’t you ban plastic in Ireland?

"We have done it from the point of view of the government," he said.

"Why we can’t do it beyond that is that I think it is going to happen over time, but you could withdraw single-use plastics from everything and it would have all kinds of consequences on the price and the availability of products and I would be reluctant to do that quickly,” he said.

What are you going to do about all the crime because children are afraid?

“For O’Connell’s, given where that school is located, we are going go ahead with the re-opening of Fitzgibbon Street Garda Station,” he said.

“That is currently being renovated and when that is open that will make a difference to the crime difficulties around that school.”

How many people died of homelessness last year?

“In truth, I am not going to hazard a guess,” he said.

“The reason why is that if I get the figure wrong – which I almost inevitably will – and given that we are talking about families that could still be grappling that grief, it does feel inappropriate to me.”
