Towards the end of his speech, Mr Corbyn turned his attention to a number of the UK's billionaires.

He says: “Whose side are you on? The dodgy landlords, like the Duke of Westminster, Britain’s youngest billionaire, who tried to evict whole blocks of families, to make way for luxury apartments? Or the millions of tenants in Britain who struggle to pay their rent each month?

“Whose side are you on? The bad bosses like Mike Ashley, the billionaire who won’t pay his staff properly and is running Newcastle United into the ground? Or his exploited workforce, like the woman who was reportedly forced to give birth in a warehouse toilet because she was terrified of missing her shift?

“Whose side are you on? The big polluters like Jim Ratcliffe, Britain’s richest man who makes his money by polluting the environment? Or the children growing up in our cities with reduced lung capacity because of choking pollution?

“Whose side are you on? The greedy bankers like Crispin Odey, who makes millions betting against our country and on other people’s misery and donated huge sums to Johnson and the Conservative Party? Or are you on the side of working people, the people who create the wealth that’s then squirreled away in tax havens?

“And whose side are you on? The billionaire media barons like Rupert Murdoch, whose empire pumps out propaganda to support a rigged system. Or the overwhelming majority who want to live in a decent, fair, diverse and prosperous society?"

Mr Corbyn says Boris Johnson "thought he was being smart" calling this election during a cold winter period, but adds he has a message for the PM.

He says: "He thinks you won’t go out to vote. He thinks you won’t go out to campaign.

“Well I say this: Labour will be out there in every city, town and village with the biggest and most confident campaign that our country has ever seen - bringing a message of hope and change to every community."

He finishes: "We're going out there to bring real change for the many, not the few.

"The future is ours to make together. It is time for real change."

Mr Corbyn now says the Conservatives are the "establishment elite".

He continues: "You know what really scares the elite?

“What they’re actually afraid of is paying their taxes. So in this election they’ll fight harder and dirtier than ever before.

"They’ll throw everything at us because they know we’re not afraid to take them on.

“So we’re going after the tax dodgers. We’re going after the dodgy landlords. We’re going after the bad bosses. We’re going after the big polluters. Because we know whose side we’re on."

Labour is launching its election campaign in the London seat of Battersea.

The party doggedly campaigned here in 2017, and won narrowly – it now leads the Conservatives by just 2,416 votes.

It’s a reminder that the party will have to work hard to defend seats - as well as targets held by opponents.

"Despite his denials, the NHS is up for grabs by US corporations, in a one-sided Trump trade sell-out," says Mr Corbyn.

The Labour leader then says the NHS is "not for sale".

This is followed by 30 seconds of chanting of "not for sale" from the crowd.

Mr Corbyn points out today is "the day Boris Johnson promised we would leave the EU".

"Liar," shouts the crowd.

"That failure is his alone," says Mr Corbyn. "After three long years of Brexit division and failure from the Tories we have to get this issue sorted."

He proposes taking the issue "out of the hands of the politicians" and asking them to trust "the people to have the final say".

Labour will sort Brexit in six months, he says, adding: "It really isn't that complicated."

Reality Check

Jeremy Corbyn claims the Conservatives would risk handing NHS money to "big drug corporations in America and around the world" in a post-Brexit trade deal with the US.

In June we asked, could US companies run NHS services?

This wasn’t exactly a pitch for the centre ground by Jeremy Corbyn.

His tone was uncompromising.

It’s designed in part - just like in 2017 - to enthuse younger voters and previous non-voters, convincing them that politics can make a difference.

But he is also searching for a message that might appeal beyond Brexit - to potential Labour voters in both Leave and Remain areas.

It's getting a bit panto now as Labour members shout back a chorus of "no" when he asks whether his promises are too much.

Mr Corbyn now proposes "30 hours free childcare for all two to four-year-olds", which is met by a loud "yes" from the crowd.

He follows this by pledging "an end to tuition fees at university".

"Is that too much?" he asks.

Mr Corbyn is now outlining his plans, which are all followed by the question: "Is that asking too much?"

He says: "A health service that people can be proud of where tens of thousands of cancer patients aren't waiting months for treatment and prescriptions are free throughout the country - is that asking too much?"

Continuing his speech, Mr Corbyn says: “We put our faith in the British people’s spirit and commitment to community. It’s your country.

“That’s why we stand with you. We stand for the many.

Boris Johnson’s born-to-rule Conservatives protect the privileged few, he says. "They’ve slashed taxes for the richest and vital services and support for everyone else.

“But real change is coming."

Set to the backdrop of a building ravaged by fire in recent years, but now artfully restored, Jeremy Corbyn is outlining his party's plan to "transform" Britain.

Standing alongside his shadow cabinet, Mr Corbyn tells a mixture of reporters and Labour members in south London that they could have "filled this hall several times over", such is the "enthusiasm" for Labour's campaign.

After briefly thanking Ms de Cordova for "everything you do" in her constituency, and his shadow cabinet for the "brilliant work" they do holding the government to account, he launches what he says will be "the most ambitious and radical campaign this country has ever seen" to bring "real change to all parts of this country".

Ms de Cordova goes on to say Labour will "end the privatisation of our NHS" and build "more homes for people to buy and rent".

To tackle the climate crisis, she says, Labour's "Green New Deal" is the only solution.

She now introduces Jeremy Corbyn to the stage.
