Muna Cali, Enam Haque and Fartun Ismail have all won - marking the first party, other than Reform UK, to do so on this council so far today.
It's worth mentioning that unlike North Northants, we're not getting a breakdown of the vote here just yet.
Back to North Northants for a second, as we've just had the result in Oakley ward.
It's a hat-trick for Reform UK, as the party secures three seats with Trevor Conway, Frank Kilgallon and Barry Lumsden.
They got 1,299, 1,162 and 1,160 votes respectively, fending off Labour with the second highest amount of votes in the region and the Lib Dems in third.

There is an obvious divide at the count - Reform candidates and supporters can hardly contain their delight about the result that seems to be unfolding here.
They are gathering around the stage in eager anticipation for each result and cheering wildly when they chalk up another win.
Their candidates for Upton ward are not actually at the count, but that hasn't dampened the celebrations.
The only question for the people representing the traditional major parties is exactly how big the scale of the losses could be.

One Lib Dem candidate has just told me his "brain is mush at the moment" as he tries to process the result he believes appears to be emerging.

It has been won by Reform UK's Kathryn Shaw and Michael Stratton.

Big news coming from the North Northants count...
The leader of the Labour group, Matt Keane, has lost his seat in Corby West.

Things are moving quickly at the moment, as the result for the Lloyds and Corby ward has been announced.
Labour's Mark Pengelly won the most votes with 981, while Reform UK's Robert Bloom secured 807.
Both have been elected to North Northamptonshire Council.

Ben Jameson and Ben Williams have been elected for the Green Party in Ise ward.
It is the first time they have ever stood for election. Here's a breakdown of the votes:
Image source, Martin Heath/BBCJonathan Harris, deputy leader of the Lib Dems in West Northants, says people are angry with the Conservatives and Labour.
"Clearly, people are looking for something different and feel frustration and anger," he tells us.
Harris claims many people on the doorstep get mixed up over what a local council's powers are.
"I think we've been very much jaded with the national picture and we spent a lot of our time talking to people about 'this is a local election on local issues'," he continues.
"Some of the things you are hearing from national parties are not things that a local council can influence."
Image source, Sam Read/BBCMark Arnull, who is standing for Reform UK in West Northants, believes "there is a possibility" his party could seize control of the council.
He claims this would represent a "seismic change" in the region's political landscape.
"Some in our party might call it a political earthquake," says Arnull, who is also chairman of Reform UK in North Northampton.
He said if the party got the majority, it "would be a landslide".

Much like what Martin has been told in West Northants, Labour here in North Northants are also not feeling too optimistic.
They fear it could be bad in Corby, which has been long been a stronghold for the party.

Reporting from the West Northamptonshire count
I've just been told by two senior Labour sources in West Northants that they expect today's results to be "disastrous".
Image source, Martin Heath/BBCIndependent candidate Ian McCord has just revealed the cheeky request he was making to voters on their doorsteps.
Deanshanger ward, which he is fighting for in West Northants, is electing two councillors - so he told people to give their first vote to their party of choice... And their second to him!
He knows the game, having once led the now-defunct South Northamptonshire Council.
If you don't ask, you don't get, and all that.
