It appears that the great Mandelson Brown feud is coming to an end. A Brussels source tells The Guardian, "There has been a fairly major shift in how these people interact. It is much warmer. These are two politicians who had differences over a period of many years. They are getting it together again."
If Brown does end up asking Mandelson to stay on in Brussels, it will show that he really is capable of forgiving and forgetting. But the real test for Brown is whether he is prepared to bring others of immense talent who he has fallen out with over the years into his cabinet which desperately needs strengthening.
