That's why the Channel 4 report into Council spending on foreign travel is very relevant.
I recommend you look at the spreadsheet, and go down to No 40.
That's the 40th highest spend out of 336 councils.
BTW, although I had foreign trips when I was a Councillor, each and every one was paid for by third parties in my role as KIMO Vice-president and then President.
(Thanks to Freddy for the pointer)
