That's 15 versus Glasgow's 25, all of which are in the above Glasgow list save Aberdeen, Edinburgh, Gurensey and Inverneess, so sorry, but that's an awful lot more domestic connectivity than MAN regardless of spin.
It also shows that London is missing some major connectivity from the likes of GCI / JER / IOM / INV, unlikely to be connected by rail.....
