Apologies for the post delay - we had some technical problems with our poll host and the poll didn't work correctly.
Welcome back to the Doctor Who 2014 World Cup! Last week's poll saw a runaway victory for a certain episode in the Series 3 qualifying round - and you can check out the latest four stories to qualify for the group stages on our World Cup page.
If you're new to the World Cup, here's a quick explanation. There are eight qualifying rounds - one for each series plus the Specials, from which 32 stories progress (the top four from each qualifier). The group stages follow, from which the top two from each group of four stories progress into the classic tournament-style knockout rounds. Eventually, two stories will reach the final, with the winner being crowned World Cup champion!
We're continuing the qualifying rounds today with Series 4, David Tennant's final full series as the Tenth Doctor. Series 4 saw Donna Noble step aboard the TARDIS, the introduction of River Song and all of reality becoming under threat - but which story is your favourite? You can vote below for your favourite two stories of Series 4!
The poll will be open until Friday 28th February - so please get your votes in before then! We'll have the results as soon as the poll closes on our World Cup page - and come back next Saturday for the Series 5 qualifying round, where Matt Smith's first series as the Eleventh Doctor will be voted for.
