Well, I have limited news so I don't know if he has announced this or not, but my first thought would be to deploy air defence destroyers/ figates. .
Remember when the Houthi were firing missiles and drones at shipping in the red sea, a big deal was made about how our brit ships were shooting them down. These things are supposed to be able to detect and remove swollen gonads on seagulls. Or so they claim, sort of.

We spend billions and zillions on this stuff, so if I was Cyprus, the opposition, or the free press, I would be asking where are they ?
And if we don't have any available, the next question should be "why fucking not ?"
That last bit is a bit TIC, but seriously, I have not seen it mentioned on the news. So are our ships in port/drydock/deployed etc. Two weeks ago Starmer said he was sending a carrier to the Arctic, to defend Greenland against no threat. So now something is actually happening, where is all the stuff we have for when things happen ? So send a carrier group with it's air defence escorts, and our F35s with their advanced radar.
And it's the eastern med. A long way from Iran. Not a threat to anyone. Sure, it's crowded with EEZ waters, but send first, ask for permission as they are en route ?
Re the drone attack on Cyprus. My first thought was a sleeper cell local. Small drone and all that. Lebanon makes sense, but Iran no. Too far, has to go over too many countries with twitchy air defense etc.
