"A Lira is 20p now!"
"Nearly, but not quite."
Hooray! To add to the celebratory atmosphere of the new CBF both Fabian and JohnF are right!!!
Google does indeed report that
1 Turkish Lira equals
0.20 British Pound
That is because it takes the pound to two decimal places and, quite properly rounds down to 0.20.
XE, on the other hand, states it to six decimal places as:
1 TRY =0.204149 GBP
