That looks like the hanger has broken, not the mech?

Any fix other than a new frame/bike?

Mech hangers are sacrificial. The idea is they brake off so they don't destroy the frame in the event of impact.
You can get replacements as said upthread. Just need to search online. They are usually specific to bike or bike brand.
Google search Giant Defy mech hanger throws up several options at a tenner.

Unbolt the rear derailleur hanger from the derailleur and the frame, and order a new one. It should be a fairly easy match as it's a common bike.
When the new hanger is fitted, make sure that the high/low limits are correct.
And order a spare hanger for next time.

"Giant Defy hanger" jgi
Get friend to unscrew broken bits (still attached to frame and RD) to see the correct shape. LBS if unsure. Once obtained 5 minute fix.

Educate me please, just looked at both my MTB's & the hanger is screwed on from the front, this looks like it's screwed from behind.
The bike is a Giant Composite, circa 2012

Thank you all, rang Giant in Sheffield with his serial number & they confirmed he needs a 1159-RE171A-003 which they have in stock, so he's on his way down.

Regret @smokeysmoo 's link only goes back to 2014. This is a Giant Defy Composite 2012.

Yup. Identify the right hanger and it's a 10 minute job.
