I thank the 16 Senators who spoke for their contributions on the Order of Business.

I share Senator Catherine Ardagh's concerns about the help-to-buy scheme and thank her for raising the matter. The scheme was established by the Government to help first-time buyers, given the critical difficulties in the market. The Government made no apologies for doing so because it wanted to promote home ownership and allow people to buy.

Any roadblock should be ironed out and the scheme immediately changed. It is important that we allow for it to work and, if there are teething problems, for them to be ironed out. I will be happy for the Minister to come to the House to discuss the issue. In order to expedite the matter, I suggest the Senator table a Commencement matter on it because it is important and I share her concern about it.

Senators Catherine Ardagh and Kevin Humphreys raised the issue of air pollution and referred to the impact it was having on the lives of many homeowners and residents in the city of Dublin, in particular. It is a source of concern that in 13 of the areas mentioned air quality is inadequate. It is important that the Minister for Communications, Climate Action and Environment, Deputy Denis Naughten, and the Environmental Protection Agency be allowed to work together on the matter. It is clear that there is a need to consider other initiatives and schemes for diesel cars, as Senator Kevin Humphreys rightly said. There is a proposal to ban the use of diesel cars in some European cities. The Government has taken initiatives to improve the quality of vehicles, but it is a good idea to invite the Minister to come to the House to discuss the issue.

Senators Gerard P. Craughwell, Michelle Mulherin and Terry Leyden referred to Brexit. In the context of the cross-Border health initiative mentioned by Senator Gerard P. Craughwell, there is very strong North-South co-operation on arrangements and protocols in the health sector. Senator Frank Feighan made a similar comment. I will be happy for the Minister for Health to come to the House to discuss the matter raised by Senator Gerard P. Craughwell. If he has a specific medical care issue, he can come back to me because there is a very good North-South relationship, with people being treated for various conditions in hospitals in County Donegal, Altnagelvin and Craigavon.

Senator Rose Conway-Walsh referred to the scandal of tracker mortgages. All of us in the House support the people with tracker mortgages who were affected. They were the unwilling victims of the crisis. However, the Senator did not mention that the finance committee of the Houses of the Oireachtas was investigating the matter. The Governor of the Central Bank was before the committee prior to the Christmas recess. The Central Bank is undertaking an investigation and that work is under way. The report will be brought before the committee. The Governor of the Central Bank will also come back to it. It is important that people be put on the correct rate. As the Minister for Finance, Deputy Michael Noonan, said last night, people should be punished for wrongdoing in that regard. It is a little opportunistic of the Senator to come into the House this morning and not give credit to the Oireachtas for the work that is under way. We all share the sentiments underlying the thrust of the motion that those with the wrong mortgage, the victims, should not be penalised and that people should be taken to task for what has happened.

Senator Frances Black referred to the very tragic death of Shane O'Farrell. I join her in sympathising with his family and will ask the Tánasite and Minister for Justice and Equality to reply to her request. I do not know what the up-to-date position is, but any measure that could give solace and comfort and a sense of closure in the investigation of the cause of death should be considered. I cannot give any commitment, but I will ask the Minister to liaise with the Senator on the matter.

Senator Kevin Humphreys raised the issue of bogus marriages. I join him in commending all those involved in dealing with the issue. I pay tribute to him because in his former guise as a Minister of State he was very proactive in dealing with it. We also worked together on it. We must be very vigilant because, from the events at Dublin Airport this week, there are many ways by which people try to come into the country and stay here. The Senator has, therefore, drawn attention to a very important issue.

Senator Maria Byrne mentioned Ruth Negga and her Oscar nomination. I wish her well and hope she will secure an Oscar. I will be happy to have the Minister for Arts, Heritage, Regional, Rural and Gaeltacht Affairs come to the House to discuss the arts.

Senator Terry Leyden also referred to Brexit and asked who was involved in the negotiations. The Taoiseach is the lead person in the Government.

That is the problem.

The Taoiseach has appointed Mr. John Callan as a second Secretary General to lead a new division in the Department on Brexit. It is important that we put Brexit in context. The Government is not standing idly by on the issue. The Taoiseach is not sitting in his office twiddling his thumbs. He is travelling throughout Europe and negotiating quietly and effectively with other European and world leaders. It is important that we remain committed to securing a very good deal for the country. I accept that there are huge challenges facing it. Those of us who attended the briefing by IBEC this morning and understand the issue from our dealings with various organisations realise it is important that there be a co-ordinated approach. I accept that Senator Terry Leyden is involved in the Parliamentary Assembly of the Council of Europe, but it is important that we do not try to score political points. We must ensure we retain a strong interest in the context of the North but equally in the context of the component parts of the economy.
