Can my DD take the children in these circumstances?

Sorry this will be long: I desperately need advice

For background - My DD has two small daughters (both under 7) with her ex partner. They split up two years ago, he still see's the children but my DD has custody of them both. She and the kids live with us (myself and DH) at the moment. DD has some learning difficulties related to an accident she suffered as a teenager and struggles to care for her children without heavy support. Because of this myself and my DH do a lot of the childcare for our dgd's.

About a year ago DD told us that she had a met a new boyfriend online. She bought him round to see us soon after and introduced him to the kids. A couple of months later she asked if he could move in because he was being evicted from his accommodation. I said no. DD had a huge strop at me and declared that she would move out then. I said fine. Heard no more about it from her (she quite often says she'll do stuff in the heat of the moment then doesn't bother) until I came back from work on Tuesday. DD was not at home and most of her stuff was gone. I rang her and asked where she was. She said she was with her boyfriend (in his hometown) and they were moving into a flat together that day.

The flat (that she hadn't told us about) is nearly 100 miles away from us and all her close family (it's in the same area that her boyfriend is from) . She's now saying that she and her boyfriend are going to come back and take the children to live with them on Monday.

I have serious concerns that the children won't be looked after.

The few times that DD has had the children alone (without support) have not gone well. She doesn't spot potential hazards (ie: she left on a hot iron unattended in DGD's bedroom and one of the kids caught her arm on it) another time the younger dgd was nearly hit by a car because she didn't hold dgd's hand whilst crossing a main road.

She doesn't plan anything in advance or think ahead. This often means she doesn't have food in the house or she'll forget to collect the kids from school unless we remind her. She has no new school organised for them currently, she says she'll look for one after Christmas...

The few times I have met her boyfriend I have been concerned about his behaviour towards dd. He's very posessive and overbearing. If we went out for a meal for example then he wouldn't let DD go to the loo by herself for example. He would insist on waiting outside the toilet door. He also answers her phone for her and opens her post. He has his own children but he has no contact with them

When they turn up on Monday can I refuse to let the children go with them? I've suggested to DD that she comes back and we discuss it but she's insisting on taking them Monday. I'm very concerned for their welfare
