I noted the comments left at the foot of the article suggesting what the security services used? The SAS, MI5 and MI6 don't need one of these tech vests as they have wrist watches that do the same thing, and much much more. Besides in this hot/sweltering weather it might look odd someone walking up and down in overdressed (garment/s) to conceal the vest. Perhaps the spies only come out during the winter months. The version for tropical Islands/seaside is incorporated in a scuba diving suit (which the good guys from MI5 wear over their dinner jacket, normally) <img src="images/smiles/icon_eek.gif" alt="Shocked" title="Shocked" /> .
Deemed possible (though not very practical):

Some UK newspaper are seemingly going on on anything - even vaguely - connected with NSA, surveillance, big brother (and what not).
