I want to put down either laminate or ceramic floor tiles on top of the existing two layers of tiles. I can't face digging the whole lot up and putting down a membrane; would a liquid DPM work e.g.
Any advice welcome.

I've used Wickes liquid DPM (which is a paint-on rubber/bitumen) under a couple of inches of Wickes deep base floor levelling, with good results.
I have used an F Ball epoxy DPM on my kitchen (same problem as you). F75 IIRC - you should find it on their website.
If your tiles are glazed you'd only need to dampproof the joins. I don't think I'd put bitumen or any other bulky paint on under new tiles, better to use something that soaks in.
