Fixed window drainage holes?

[Johnytuono]

Water leak from internal beading, I'm assuming either there is no (concealed?) drainage holes or they're blocked or maybe even the packers are blocking them? If I 'press' the bead, top or bottom, a bit of water comes out. It''s been going on for quite a while, I spent all summer making sure there's nothing 'above' allowing water in and am pretty sure thats not the cause of the problem.
I have attached an external view of the window and am unsure if the bottom rectangle should not be sealed where it meets the brickwork (above it is clear but obviously can't see in the gap with it being so small and anyway with it being concealed I wouldn't (or shouldn't) be able to see anything? If I take the internal bead out do you think it would be worth drilling a few holes, would I maybe even be able to see the problem? These were fit by Safestyle by the previous owner so I'm not confident on the fit.
Thanks

EDIT: Looking at it, is that bottom rectangle just some sort of square trim filler do you think?

Take glass out and have a look.

I'll add.
Mother in law had similar and I foamed around the outside. That stopped it for a few years.
Ended up with a new window and fitter said it was never sealed in properly.
So it could be blocked drain holes, or not masticed around to seal in.

Hopefully sorted if anyone else may have a similar problem.
Removed the bottom bead and noticed there was no way any water could get out to the external concealed drainage holes (I found 3 in the external frame and cleared these with a paper clip just in case). Anyway. drilled a few holes so it 'connects' to the same channel as the external drainage holes, poured some water in and it drained off.
Fingers crossed

Hopefully the holes you've drilled are into the outer chamber only.
The other reason you can get water coming up the beads internally is a build up of pressure within the frame . This is much more prevalent on very wet and windy days though

Yep, definitely.
