minority but not a majority it would be around 307-310 seats, compared to labour + SNP of 322-327
And 283 seats for the conservatives is on the high side of most predictions.
An average of 5 professional forecasts is 277 seats for the Conservatives and 269 for Labour. The Li Dems average 26.
However you can't add a LibDem average and a Tory average together since they are not exlcusive, polls that have the Tories doing better comes at the expense of the Lib dems, partially.
The Conservatives need to do very well, get very lucky in a lot of marginal Labour seats, prevent the UKIP getting more than about 1 seat. The Lib Dems then have to do very well in marginal Labour seats, and it would help with the SNP have to win every marginal labour seats.
That is possible but it isn't what the current predictions are. It is just easier for the Labour as long as the SNP vote yes to Labour and no to the Tories.
things have got slightly closer in the last 2 weeks though, a fortnight ago Labour was predicted to win more seats than the Tories. And part of the reason the Tories are gettign mroe seats is the UKIP vote is dropping:
