Look ahead to Thursday: Corbyn speech and EU countdown
To the victors the spoils... Vote Leave and Britain Stronger in Europe are celebrating this evening after being awarded lead campaign status for either side in the EU referendum. But are Vote Leave's celebrations premature? Leave.EU, which was backing the rival Grassroots Out application, has said it is considering a judicial review of the ruling and will make a decision tomorrow. They will have to be quick. The official campaign period for the EU referendum starts on Friday. And before that, we have Labour leader Jeremy Corbyn's first major speech on the EU vote coming up on Thursday.

Arron Banks, the millionaire businessman behind the Leave.EU group, has been explaining his decision to seek a judicial review of the decision to name rival Vote Leave as the official lead Leave campaign in the EU referendum. He has said he is "thoroughly unsatisfied" with the outcome.
Quote Message: There are a number of judgements according to the Electoral Commission’s own criteria that do not make sense and we shall be raising those inconsistencies in our action. It is to be regretted that this process may put the referendum back until October but if we are to avoid the most important vote of our lives being rigged then I feel duty bound to take this course of action.”

Why Vote Leave beat Grassroots Out
The battle to become the official campaign to quit the EU has finally been settled by the Electoral Commission.
Its decision means Vote Leave gets increased spending limits of £7m during the campaign period, campaign broadcasts and a free mail-out to households.
But why was Vote Leave, not the rival Grassroots Out organisation, chosen?
Leave.EU calls Electoral Commission's decision a 'stitch up'
Leave.EU head of communications Andy Wigmore has said it believes the Electoral Commission decision has been a "stitch-up" and it is consulting lawyers.

Was it because of the tie?

Peter Bone, co-founder of Grassroots Out, tells the BBC the group "will continue to campaign in our own right" ahead of the in-out referendum on 23 June.
Asked if he's disappointed at not getting the official designation, he says the only thing that matters is if the UK votes to leave the EU.
"Would I like to have won it yes? But will Vote Leave winning it make any difference? Not really," he says - before quipping that GO's fluorescent green tie, which he can be seen sporting, is the reason it didn't get the designation.
Farage: I'll try to bring leave campaigns together
Mr Farage said regardless of whichever campaign got the designation "UKIP would always have played a big role in this campaign". He added:
Quote Message: I have always wanted all on the Leave side to come together and have done my best to try and make this happen. I'll continue to do so in the run up to the referendum to ensure the Leave side wins. We in UKIP, as I've said from the start, will work with anyone that wants to leave the EU. We must work together to get our country out of the European Union."

Farage: Immigration is the key issue in the referendum
Here's some from UKIP leader Nigel Farage's statement responding to the news that Vote Leave - and not Grassroots Out, of which he is part - has got the official Out designation.
Quote Message: The decision of UKIP to back Grassroots Out was on the basis that they saw the importance of the immigration issue in this referendum, and that we wanted to reach out across the country at a grassroots level and work with everyone from the left, centre and right of British politics to get our country out of the EU. I believe this approach is the only way the Leave side can win this referendum. It is clear that Vote Leave now share my view on this approach, for instance the issue of EU open borders is now a prominent part of their campaign messaging."

Quote Message: I’m delighted that the Electoral Commission have recognised that Britain Stronger in Europe has the breadth of support, the unity of purpose and the campaigning organisation to be the official Remain campaign in the upcoming referendum.
