Who would have believed it? I have just seen Margaret Thatcher walk back through the door of No 10. This - her first visit in seven years - was revealed with great glee by Team Brown.
Team Thatcher say that she is happy to receive praise from where she can get it. When I asked if that applies to praise from David Cameron the arch reply came "Perhaps we missed it".
When I suggest to Team Brown that they are without any shame they reply that "psychological warfare" is critical in any election.
Lest I over analyse the political game playing - perish the thought I hear you say - it's worth pointing out that this is a courtesy visit arranged by a man who - though a bitter political opponent of Thatcherism - remembers her invitation to him as a young backbencher in 1983 to meet her when she was PM.
