These white spots have just appeared on my cherry tomato plants. In addition there are some holes in the leaves. What is the diagnosis and treatment, if any? Thanks in advance.

Tomatoes with leaf damage can have a variety of causes. The holes could be from flea beetles or frost damage from the spring that is usually white or tan and then the dried area in the center of the spot can fall out. If you don't have symptoms on new leaves, then it could be a flea beetle attack that is now gone or a plant dropping damaged tissue from frost damage.
But also, the tomatoes could have one of the leaf spot diseases with tan or black areas that also have a hole in the middle as it matures, looking like a shothole.
