Brake problem...please help
Discussion
Peugeot 207. Front discs, rear drums.
Brake pedal has very little resistance and goes all the way to floor with ease. Brakes as a result are incredibly sharp with no progression. Pumping pedal has no effect.
Recent new discs, pads and fluid.
Someone mentioned to me that it was the handbrake that needed adjusting. Is that likely the cause?
Can anyone please help?

Stationary with engine off, pump the pedal and see if it comes up and holds a hard pedal. If not, try it with the handbrake on. Pedal should sink only a little when started and the servo operates.
Possibles are
air in the system - try bleeding again. pump the pedal 4 or 5 times while someone opens each bleed nipple letting the pedal go almost to the floor before shutting the nipple and repeating 4 or 5 times per caliper.
Could be sticking or dragging calipers though car would probably pull to one side.

Sounds like a possible master cylinder fault or your rear brake cylinders are leaking heavily. Either way it needs to come off the road and get checked out immediately.
It could also be a ballooning brake flexi hose, which feels a bit similar. Either way, brakes are not something to cock about with - get it checked out.Have you had the rear drums off?
Poor adjustment of the shoes would give you excess travel (although pulling the handbrake up should improve that)
Excessive brake dust build up would make the brakes snatchy, but this only tends to happen for the first few brake application after the vehicle has been standing
Leaking rear wheel cylinders would give you a soft pedal, but to be as bad as your saying it would be quite a big leak, and you'd notice the fluid loss.
Was it doing this before the pads/discs/brake fluid change or were these things done to try and fix the problem?

^^^^ ThisSounds to me like air/something in the brake lines - I wouldn't entertain driving it 'til I'd bled the brakes then re-filled the fluid. Sticking caliper possible but not likely IMHO. Get it done yesterday. One time you WILL have no brakes at all.
Should it happen after re-doing the fluid, then you have a leak, I'd take an educated guess at.
Air in system/balloning pipe, if not it's quite likely to be a servo problem. If it was leaking you would have no brakes at all by now, anything else would probably invole dragging to one side or front/rear.
Either way brakes are not something to work around, do it once and do it properly.
