Both the trap and waste are brand new and of good quality. No corrosion. I think I will try the layering of PTFE tape on the top of the spigot washer. I can access this area without removing the bottom compression fitting with watertight currently.Is there a rubber washer on the top of the trap where it fits to the chrome waste?
Is the bottom face of the waste flat and not corroded and if it's plastic not split?
Is the leak from the trap to waste connection from below the spigot nut or above, if above it can sometimes be the chrome waste (if it's not new) has corroded within the thinnest part of the thread and is leaking down and over the nut?
If after a couple of attempts the trap to waste still leaks, get some PTFE, roll it up like string and wrap a few turns just above the top edge of the washer, it'll push up into the bottom of the waste and provide a larger sealing surface.
In the past where the bottom of the chrome waste has corroded I've removed the washer and wrapped many turns of ptfe to create a large soft seal.
As BEN has said, the lower compression joint will normally seal with quite a noticeable misalignment.

I used the PTFE layering technique snowhead suggested earlier today on the spigot joint. This sorted the problem instantly.Something is very wrong if you can't make that water tight.
That's not misalignment by any figment of imagination.
Get some new rubber seals. Make sure they are the correct ones
Ben-geeJust make the joint as I told you earlier. Do the nut up by hand , it should run freely and then resistance is felt- at that point give it say 1/4 turn more.
Test and if leaks then nip 1/16 turn and repeat.
The trick is do not over tighten.
This is what I’d was referring to as skill and experience- we just get it right first time by feel. But the above method will work if followed.
