What Was This Mystery Flying Boat of 1935

The British 200 ton project was to have eight engines for a grand total of 30,000hp. That means engines with, in 1935, a highly optimistic 3,750hp apiece. Supermarine? Saunders-Roe? No idea.
The Latécoère 65-80 ton study could be one of two configurations described in Latécoère - Les avions et hydravions by Jean Cuny, Docavia/Éditions Larivière, 1992.
1) A study with eight Hispano-Suiza 14 Ha radials, each 1,000hp at 2400m
2) A study with six double Hispano-Suiza 24-cylinder engines, each 1,700hp at 2400m (double Hispano Suiza 12 Ybrs in the article)

Study 2) fits the article's description of the Latécoère study best.

I also found a lot of french links, Britain had plenty of engine manufacturers, so why would they fit french, unless for a french customer?

So something bigger than a supermarine 179?

Apologies in advance if I misunderstood your reply.
Hesham's French article only mentions Hispano-Suiza engines in connection with the Latécoère study.
With 80m fuselage length, 100m span, 200 tons weight - numbers from Hesham's article for the British project - yes, much bigger than the 179 with its 53m/174ft span (number quoted by Ralph Pegram in Beyond the Spitfire).
