AS TONY BENN ONCE SAID, POLITICIANS CAN BE SPLIT INTO TWO CATEGORIES. THERE ARE THE SIGNPOSTS WHO SAY “THIS IS THE RIGHT DIRECTION” WHATEVER THE WEATHER. AND WHETHER YOU AGREE OR DISAGREE, YOU KNOW WHERE THEY STAND. THE OTHER GROUP ARE THE WEATHERVANES WHOSE POSITION ALTERS WITH THE CHANGE OF WIND. POLITICS NEEDS MORE SIGNPOSTS; I’M GRATEFUL THAT WE HAVE ONE IN JEREMY CORBYN.
