Leaking valley

[foxhole]

Cleaning out the loft found a rotten piece of tile batten, this was one supporting the tile valley so have a slight drip coming thru.
There is no lead or anything under the tiles [valley just done with tiles].
Whats the best way to remedy?
[May consider a new roof come the summer as its very tired and has no underlay, been there probably since the 30's]

Probably a cracked tile either at or above where you are getting the ingress.

At the age your roof is the tiles will probably be brittle and difficult to repair without breaking others around it.

If you can identify the cracked tile in the valley you can slip a piece of sheet lead under it.
