I'm completely stuck on how to move on with this Sudoku - what's the next number?
It's from The Times puzzles - number 12583 on 13/08/21

One possible next action involves the fifth row.
R5C2 can only be a 2 or a 5.
R5C4 can also only be a 2 or a 5.
This "naked pair" means that in the other locations in row 5 there is no 2 or 5.
In particular, R5C5 can now only be a 1.
Further deductions are all straightforward.
