YouGov/Sun - 42/39/9
YouGov's daily polling figures today are CON 42%, LAB 39%, LDEM 9%. After a week or two of the two parties being neck and neck YouGov has shown the Tories ahead for three days in a row now. True, we're within the margin of error of the two parties being equal, but it's been three weeks now since YouGov briefly showed Labour moving ahead, so the underlying position would appear to be a very small Tory lead.
Other polling companies are still displaying a Labour lead in their most recent polls - though for Ipsos MORI and ICM those polls were around the time YouGov were showing a Labour lead, so they too may show the Conservatives recovering once their December polls appear (for Populus it's even longer since their last poll, they didn't seem to do a Times poll in November for some reason).
