Could be deterioration to an existing appliance. Have you suggested removing loads?

Have all the current appliances on the ring been disconnected? If not that's your first point of call.

Clamp the circuit to see what load is on it.

Pull the breaker out and inspect it closely. look for hairline cracks around its casing. I had this years ago, and a simple replacement MCB fixed the problem.
The one had a problem with was a MK one. MCB's although reliable dont last forever. for the sake of 10 minutes and a couple of quid just fit a new one.

if it's a 30A it's quite old, esp if it's the push button type. if the load is normal, it's probably had it's day.
