The Euro election results will probably give a better indication of nationwide feelings etc.
However, it is fair to expect more of the same.
Thr only hope Labour have, and it is a remote one at that, is to replace Brown immediately.
Unfortunately for them I personally can't think of any creditable and viable alternatives who could do the job and appeal to the electorate.
Freeborn is right that the EU elections will give us a better indication but if you want to look back to history, the end of the last Tory Government
under John Major is worth reviewing.
The current Government has 350 MPs but I guess that the next Government, which I guess will be Tory will have in the order of 450 seats, given them a
working majority in the order of 200. The big discussion point would be the number of seats split between Labour and LibDem.
