Many thanks for the replies.
I found the following Airbus document. Page 5 seems to show it quite clearly.

It states that the minimum thrust speed usually equals about 1.35 to 1.4 V stall in landing configuration.
It also states that the minimum final approach speed is slightly on the back side of the power curve.
