I'm pretty sure in her memoirs Thatcher says she'd have gone for an election in 1991. That said, Thatcher ITTL has been pretty badly weakened, and I think even she is going to have some compromise forced on her by Hurd, Major, et al, so the Party may "strongly advise" the PM to hold on until 1992. Whatever the case, the ensuing election will be interesting. Thatcher's ratings in 1990 were, iirc, well below the levels they had been prior to the victories in '83 and '87, and even allowing for the usual swingback towards the Government, the Tories would have a mountain to climb. I think on balance, a Labour victory in this election is probable, although the Kinnock factor will certainly work against them. All outcomes here are possible, ranging from a small Labour to a small Conservative majority. The one thing I cannot see is a decisive victory for either party.
