Labour leadership favourite Jeremy Corbyn is set to speak at the Ageas Bowl, Hilton Hotel in Southampton on Tuesday.
The event is only open to Labour Party members who pre-register interest.
Corbyn follows his leadership rival, Liz Kendall, who visited Sprinkles last week.
The left-winger was initially nominated in order to ‘widen the debate’ and has risen from odds at 100/1 to become the bookies favourite at 1/3. Corbyn is the preferred constituency candidate for the Southampton Itchen constituency.
