Agreement on 50p tax rate

Apparently Alan Johnson now agrees with Ed Miliband that the 50p tax rate will be needed at the time of the 2015 election.

Why am I reminded of the fourth Star Trek movie, "The Voyage Home", where they're in Dr Gillian's pickup truck and deciding what to dine on that evening. Spock at first says he doesn't like Italian cuisine, but in the end, after a bit of to-ing and fro-ing with Kirk, he says he does. Interestingly, in the event Spock gets left behind anyway.

I wonder whether the same will apply to Johnson...
