On Monday I was in the Chamber to hear the Home Secretary make a statement on the absolutely disgraceful Windrush scandal, and we also called her to appear before the Home Affairs Select Committee this week.

It really is a disgrace that people who came to our country and contributed huge amounts have now been left high and dry by the Home Office, and we have heard some really shocking cases.

It is also my view that the ‘hostile environment’ policy which has led to this terrible situation - instituted by the Prime Minister when she was Home Secretary and continuing under the current Home Secretary - needs to be abandoned, because it’s not just affecting the Windrush generation but also many others.

I asked the Home Secretary: “The impact of the contributions of generations of Africans, Caribbean people, Somalilanders, Yemenis, Pakistanis, Indians and Bangladeshis runs throughout my communities for everyone to see. Does she accept that the ‘hostile environment’ policy has affected not just the Windrush generation but generations of people from other communities?”

I see mistakes being made every week that affect constituents – and some are heartbreaking cases. Fundamentally this is also a reflection of the cuts in the Home Office, and shows the absurdity of the current plan to spend nearly half a billion on preparations for Brexit last year and this, instead of spending that money on sorting out these messes or for example on new police officers for our streets instead. It’s an extraordinary situation to be spending that on their reckless Brexit.

We have an important Brexit debate today (Thursday) about the Customs Union – as regular readers will know, I’m very strongly in favour of us remaining inside the Customs Union, as the implications of leaving it are huge for Welsh businesses and freight transport through Welsh and Irish ports. I fundamentally believe that we should stay inside the Single Market and the Customs Union and that we need a people’s vote on the Brexit deal.

Last weekend I spoke about this and other matters, including support for the Welsh steel industry, at the annual Welsh Labour Conference in Llandudno.

Of course Carwyn Jones announced that he will be stepping down as First Minister in the autumn. There were many heartfelt tributes to Carwyn for his work in leading Wales forward, and on a personal level he has been hugely supportive of Cardiff South and Penarth over the years, and a good friend.
