Most likely cause & what to check
Remove the cistern lid and set it safely aside.
For a lever handle: check the link arm or chain connecting the handle to the flush valve syphon. This often comes off or snaps. A replacement link arm or chain costs under £5 from any hardware store.
For a push button (dual flush): the button mechanism clips into the cistern lid. Check if the rods connecting the button to the flush valve have simply disconnected — they often just push back together.
If the handle or button itself is broken or cracked, measure the thread size or take it to a merchants to get an exact replacement.
Refit the new handle or button, reconnect any linkages, and test the flush. Adjust the chain length if necessary — it should have a little slack but not so much it gets caught under the flap valve.

Frequently asked questions
My flush button is stuck down — what does this mean?
The button may have its retaining clip broken, causing it to drop into the cistern. Remove the lid and retrieve the button — the clip can usually be replaced.
