Leak between bathroom sink plug and waste pipe

[Scott walla]

I've attempted to replace the waste plug but couldn't get the nut undone but not the sink is leaking at the waste pipe connection.
I've unscrewed the large white cover and where the pipe connects with the metal sink part it is leaking, I separate the 2 parts - would plumbers mate work or is that just for sealing around a surface?
Any other suggestions would be appreciated!

There should be a black oring at this point?
Not plumbers mait, wrap ptfe tape around the top of the trap connection.

Are you on about a basket strainer waste or a trap as per @Ben-gee?

Oh yes that’s more likely on re-reading, we’ll spotted ChrisB!
