Slim, there's always the famous 'last straw' and for some people this is it.
Nobody seems to be counting the economic cost of this farce. This doesn't stop (or extend to - whichever way you want to look at it) a 'relocation' debate, London and the UK are losing a lot of tourism and stopover business. Talk to any seasoned traveller these days and mention London and you'll get 'avoid at all cost' as a reply. Never underestimate the importance of the hassle factor !
