What foundation is needed for a 65m2 flagstone patio on heavy clay?

We would like a concrete patio foundation.
Questions:
What depth sub-base?
What depth concrete?
Would steel mesh in the concrete be beneficial?
What bedding material/depth?
Is an expansion joint needed in the concrete (it will be 12m wide)?

Grateful for any paving expert advice.

100mm compacted mot if its firm clay will be more than enough

Don't over complicated it.
