Here at the headline numbers from the latest Ipsos-MORI poll:
Conservatives --- 48 percent (up 4 percentage points)
Aside from the hefty Tory lead, the unchanged Lib Dem position is worth noting - especially in view of the astonishing gains they've been making in other recent polls. I haven't seen any below-headline findings yet, but will report back if there's anything interesting.
P.S. The last time the Tories had a 20-point lead (or above) was back in September.
