In parliament, a "whip" is a member of a political party that ensures enough party members will vote for or against a bill. It's not very common to see this used as a verb, at least in the US. Here, it means that May should be talking to members of her party to ensure their support in an upcoming vote.

I was not meaning to imply you were a fool. This is a language learning site, for people learning their way around new languages. Fish is countable. It can also be, in specific uses, a collective like "we ate fish." This is true for many foods. "Chicken" for example. Fishes is NEVER correct. At least in the United Stares you will not hear a native speaker make that mistake.

One way to be more precise with the timing of a request is to use the word "right." As in: "Let me know right when you leave." This signals a request for a response at a particular time, not just information about when they plan to leave.

Countable! One fish, two fish, red fish, blue fish....
