Which is, of course, much easier said than done – a fact highlighted by another passage in Webster's report, which reveals:
It hardly needs adding that a Prime Minister who, five months out from an election, is still instructing the Cabinet to back his leadership is not best-placed to sell a bold vision to the country.“
"Mr Brown said there must be no repeat of last week’s botched coup. The campaign must be not 'about us and the Labour Party' but about the public’s priorities. Sources said that the words amounted to an instruction."
But, as Danny Finkelstein suggests in his Times column, the most worrying divide for Labour, right now, is over spending cuts rather than Brown's leadership. Alistair Darling may have injected a bit more honesty into the debate, after last week's attempted coup – but there are still signs that Ed Balls is resisting this novel approach, not least in his evasive interview with Channel 4 the other day.
