Steps on staircase dropped.

It looks a lot worse than it is! Can you get underneath?
you just have to Jack it up back into place and glue and screw the tread and riser into the newel post (refer to Freebears diagram) the riser with the metal clip can be screwed Into the back of the cracked tread.
The only problem I can see is how bad is that crack? Is that tread now in two pieces?

I have levered it up into place, but I need to take off the vertical piece of wood in order to screw a piece of wood in place to support the step.

The crack is bad, I will cover it with plywood, the step below too. It looks like it was bodged many years ago.

Just had a chance to get over to my mums but cannot access the back k of the steps due to plasterboard.

I removed the carpet from the first set steps and tried to take some pictures.

I tried to remove one of the steps but it looks to have been repaired in the past and struggling with a few of the screws which have been rounded out.

I have also noticed that between the boards there is what looks like plaster which is crumbling away.

You will need to remove some plasterboard and get at the under side of the wood to see what i going on, prob=ably some rot or worm in there.  Use new treated wood to fix it.  A cheap car bottle jack is useful to get the steps back into their correct place whilst fixing new supports.
It is a simple DIY repair job and should last many years unless the stairs are coming away from the wall.

My steps are hopefully fixed now. It is difficult to get inside, I cut one of the steps in half in order to gain access. I then screwed a piece of wood inside/below the steps in order to support it.

Just had a chance to head  over to my mums to have a look at the stairs.

I cut a hole in the plasterboard to  access to the back.

Hard to see from the pictures but the wood which runs the length of the stair case looks to have rotted away  in the section the step sits  against.

When there is weight on the step not only does it move but also that runs against the wall. 

If I was to screw a block of wood onto the wall under the step once jacked up would this help.

I cant see any rot but it does look like its already been repaired. Are the treads and risers mdf?

You might be able to support the step from the ground or repair what appears to be a previous failed repair.

Yes it looks as though someone has already attempted an repair)(mdf boards) , the boards do no run flush to the wall and may have been held in place with hard as nails which has crumbled away. 

I have used a jack to get the bottom step in place and cut a piece of wood to wedge between the bottom of the 2nd step and the floor which is holding it in place but need to figure out to secure it as there's a 1" gap between the wall and the support. 

I cannot drill into the wall due to the small access so am trying to think of an alternative.
