Before we begin the last part of this session, can I ask you to spare a few thoughts for April Jones, her family, the officers Dyfed Powys police and the search and rescue services; and for the people of Machynlleth, who have displayed such tremendous community spirit over the last seven, harrowing days.
Our session this morning has highlighted the rich diversity of the constituent nations of our country.
And the truth is that the United Kingdom has always been a collection of very different peoples.
We may not always speak with the same accent – of which Ruth, Theresa and I are living proof.
We may sometimes be bitter rivals – particularly on the rugby field.
We may also feel passionately patriotic, as Welsh, Scots, Northern Irish or English.
But one thing that we Conservatives do agree on: no matter where we come from, no matter what our accents, we speak more loudly and effectively when we speak with one voice.
As part of one strong, United Kingdom.
Our prominent role in NATO and our permanent seat on the UN Security Council are proof of that.
And our success in the Olympics and Paralympics proved the point still further.
And we all share the same values - particularly an aspiration to improve our lot - and the lot of our children, grandchildren and communities.
To make our own part of the UK a better, more prosperous place to live.
Of course, we now live in an age of devolution.
The Welsh Assembly was established over thirteen years ago, and the Welsh Government is responsible for a wide range of policy delivery in Wales.
So Wales has two Governments: one in Cardiff and one at Westminster.
For most of the time since devolution, Labour have been in power, both in Cardiff and at Westminster.
And the hard fact is that, throughout that period, Wales has become progressively poorer, not only in relation to other parts of the United Kingdom but to many other, less advantaged parts of Europe.
Everyone remembers Peter Hain’s famous gaffe, when he boasted on the floor of the House of Commons that, no matter how tough it got, Wales was at least richer than Rwanda.
But that slip-up only highlighted the truth of the matter: that after years of Labour government, Wales has declined in prosperity, to the extent that parts of it are now poorer than some parts of Romania.
And while Wales, in the days of the Welsh Development Agency, was always routinely at the top of the league for inward investment into the United Kingdom, it is now, equally routinely, toward the bottom.
Now many of the policy levers that are crucial to development in Wales – for example, telecommunications, energy, railways, and ports and other types of infrastructure – are not devolved.
Responsibility remains with the Westminster Government.
Wales desperately needs new infrastructure.
If we are to attract businesses to relocate to Wales, then they need to be assured that the transport links are fast and efficient and that they will have the most up-to-date telephone and broadband.
And we in the Westminster Government have recognised this, by committing not only to the electrification of the Great Western main line to Swansea, but also to electrifying the Cardiff Valleys line.
And here I must pay tribute to Cheryl Gillan for all her hard work in helping to secure what is the biggest piece of new railway infrastructure in Wales for several generations.
We’ve provided an extra £57 million for new broadband in Wales – ensuring that by, the end of this Parliament, Wales will enjoy some of the fastest broadband speeds to be found anywhere in Europe.
We’ve also provided £11 million to make Cardiff a super-connected city - taking ultrafast broadband access to around an extra 29,000 homes and 2,100 businesses, as well as high speed wireless to even more.
And now we want Swansea and Newport to put in their own bids for more funding.
And let me make it absolutely clear that this Government fully supports the development of a new nuclear power station at Wylfa, which is crucial not only for our national energy structure but also for the economic renewal of Anglesey and North West Wales.
So there is much that we at Westminster can do, are doing, and have done, to help rebuild the Welsh economy.
But we can’t do it alone.
Economic development is the devolved responsibility of the Welsh Government - which is, of course, a Labour government.
But let me say clearly here today that for, my part, I don't intend to allow political differences to get in the way of working with the Welsh Government in seeking to do our best for Wales.
There is, quite simply, no alternative to working together, because the Welsh economy will not achieve its full potential unless we do so.
Together, we must send out the message that we want Wales to be competitive with the rest of the world; we are not in competition with each other.
That is the mature, sensible approach to devolution that I want to take.
I want to work with the Welsh Government in seeing what more we can both do to make Wales a more prosperous country.
To look, for example, at working up business cases for such improvements as the future electrification of the North Wales coast railway line and the Wrexham to Bidston line and improving our ports in North and South Wales.
And putting in place cross-border arrangements and institutions that will help Enterprise Zones such the one at Deeside develop and grow.
In short, to make Wales a business-friendly place.
To make it more prosperous.
To create more jobs.
This is not to say that we won’t criticise the Welsh Government when we need to.
And certainly it is not to say that our excellent Assembly group, led so ably by Andrew R T Davies, will not continue to attack and expose Labour’s failures on health, education, and in the other devolved areas.
But economic renewal has got to be the top of the agenda, not just for the United Kingdom Government and the Welsh Government, but for all the people of Wales.
Wales, as part of a strong United Kingdom, with a mature approach to devolution, with both of its governments willing to work together, can have a bright and prosperous future.
That’s what I’m committed to.
That's what the Wales Office is committed to.
And that is what we in the Conservative party are committed to, as well.
