Some 70,000 K6s were installed across Britain as part of the first nationwide programme of public telephone kiosks. Now, just 10,770 remain, including two in Normandy, France, that were installed for the 50th anniversary of the D-Day landings, and a few in Malta, Bermuda and Gibraltar. But as payphone use declines thanks to the spread of mobiles, 60 per cent of kiosks are losing money, with an 80 per cent drop in the number of calls made in the last five years. In 2002 there were 92,000 BT phone boxes on our streets; now there are 51,500.
