I thought folks might find this,
PCS in Palestine, of interest. I won't quote as it's quite long, but it gives a very accurate view of the situation at least as far as I can judge.
A bit of background on the source. The PCS is my union (Public & Commercial Services). Although the general executive is currently controlled by left-wingers the author, deputy secretary general Hugh Lanning, is not a 'leftie' himself. He was part of a TUC (Trades Union Congress) delegation to Palestine.
