The BBC's chief political correspondent Adam Fleming also asks Mr Johnson about standards for UK members of parliament and Sir Geoffrey Cox, amid a political scandal in the UK - more details on that here.

"The most important thing is those who break the rules must be investigated and should be punished," Johnson says.

"For hundreds of years, MPs have gone to parliament and also done work as doctors and lawyers and soldiers," he says, which he says "on the whole" has "strengthened our democracy".

But he adds that it is vital MPs follow the rules - "you must put your job as an MP first, and you must devote yourself primarily and above all to your constituents."

Now onto questions.

The BBC’s Adam Fleming asks the prime minister if the draft COP26 text published today is the floor of where we want to go.

Johnson says it is "crucial now that we show high ambition".

"The risk of sliding back would be an absolute disaster," he says.

Johnson urges negotiators to find "the courage to get on and do it".

He says now is the time for everyone to get together to think about how we can compromise, be flexible to meet the needs of the planet.

"Here in Glasgow the world is closer than it's ever been to signalling the beginning of the end of anthropogenic climate change."

It's the greatest gift we can possibly bestow on generations to come and now is within reach, he says.

He asks leaders: "Will you help us grasp that opportunity or will you stand in the way?"

The PM says there is no excuse not to act because we know what is at stake.

He says the president of Palau says if the big economies don't do more, we might as well bomb his islands.

He says to fellow leaders they cannot now sit on their hands as the world asks them to act because the world knows what a mess our planet is in.

There will be an immense and long-lasting backlash if countries fail to act, he says.

Johnson says: "We need to pull out all the stops if we are to do what we came here to do" - keep global warming below 1.5C.

He says it's "very frustrating" to see countries that have been conspicuously patting themselves on the back for signing the Paris Agreement in 2015 edging towards default now nations are demanding payment.

The UK prime minister is now addressing the climate summit in Glasgow after the first draft of a climate change agreement is published.

Boris Johnson begins by saying they are "firmly in the hard yards". He says the nuts and bolts of international climate diplomacy negotiations are getting tough and there is still more to do.

Why Sharma believes the 1.5C dream is still alivepublished at 16:40 Greenwich Mean Time 10 November 2021

The COP presidency team briefed journalists on progress this afternoon – on the big picture and the nuts and bolts of the negotiations.

Alok Sharma says his big goal of keeping the possibility of limiting the increase in global temperatures to 1.5C by the end of the century is still alive.

He has given an update on the workstreams dedicated to detailed areas which are led by pairs of ministers from different countries.

Talks over how global markets in carbon permits might operate seem to be going well, but need some “political will” to get them over the line.

Discussions about the timeframes for future climate pledges have boiled down to two options: five or 10 years.

It sounds like there’s been less progress in other areas such as money for less-developed countries and how to measure governments’ climate change efforts.

These things are very technical but they’re important.

They’re missing from the current draft of the overall deal so it’s impossible to assess it in full, and whether they will win over countries wavering about other things.

As we wait to hear from the prime minister, a reminder that key focus in Glasgow today is getting the world to say goodbye to petrol and diesel vehicles - and going 100% electric instead.

Achieving this will be a big win for curbing greenhouse gas emissions. But it also means we’ll see a rise in an industry that historically has been far from environmentally friendly: mining.

The batteries used in electrical vehicles rely on lithium, and the World Bank expects demand of the metal to soar by 500% by 2030.

In the UK, large lithium deposits lie in the rocks of Cornwall - and plans are afoot to trial new green technology to extract it.

But it’s just one solution - and experts say we need to have an urgent conversation about how to reduce the environmental footprint of mining.

A green revolution is pointless unless the planet is protected in the process.

The draft agreement released at COP26 mentions $100bn (£73bn) in financing per year to help developing countries adapt to and tackle climate change. It urges the developed world to deliver on the pledge by 2023, after missing a previous deadline.

Why is the figure of $100bn so significant? Let's go back in time to a different age - 2009. MySpace was one of the biggest social media platforms in the world, and Donald Trump still presented The Apprentice.

The COP15 summit in Copenhagen, billed as the last chance to save the planet, external, was faltering and needed a boost. Enter Hillary Clinton, then US Secretary of State, who reportedly came up with the $100bn figure to break the deadlock.

The plan made it into the final agreement and was supposed to have been delivered by 2020. Not only was it intended to help emerging economies build infrastructure to shield them from extreme weather, but also to help them reduce emissions by shifting towards renewable energy. But this process can be costly, so - the developing nations argue - it's only natural that richer countries should stump up.

There was dismay and anger when the 2020 deadline was missed. Knowing it would be a sticking point at COP26, the UK government released a plan, just before the summit, to deliver the cash by 2023.

There's little promise of much more money in the draft text - many parties regarded the $100bn target as a floor, not a ceiling. However, there's still all to play for, because finance could be one of the keys that unlocks success at Glasgow.

We expect to hear from UK Prime Minister Boris Johnson in about 20 minutes.

Johnson has returned to Glasgow on the same day the first draft proposal was published.

Tweeting earlier, Johnson said negotiations teams are "making progress" but "need to pull out all the stops in the next few days to keep 1.5 alive".

"It’s time for nations to put aside differences and come together for our planet and our people," he added.

The prime minister's COP26 trip comes amid political controversy continuing to bubble in Westminster over the extra work some MPs do on top of their parliamentary jobs.

We've been reporting the COP26 pledge to work towards all sales of new cars and vans being zero emission around the world by 2040, and even earlier in some countries.

Some car companies - such as Ford, General Motors and Mercedes - have signed up to the declaration. However, Volkswagen is not one of them.

VW CEO Herbert Diess told an online summit the auto industry has a duty to "do our part" in the fight to tackle climate change, calling it "the greatest challenge for the coming decade".

He said the company is ramping up investment in electric cars, amid rising demand.

But he refused to say when VW could stop making combustion engine vehicles. "It may still make sense in South America in 2035 to drive a combustion engine with renewable resources," reports German newspaper Handelsblatt.

In June the company said it planned to stop selling combustion engine cars in Europe by 2035. It has previously said it wants to be the world's largest electric vehicle manufacturer by 2025.

The agreement that comes from the summit in Glasgow will "set the future for our children and grandchildren", Alok Sharma says.

The COP26 president adds that "everyone must come armed with the currency of compromise".

"We all know what is at stake in these negotiations, and indeed the urgency of our task," he says.

The first draft of an agreement from COP26 setting out how the world will tackle climate change was published earlier today.

It calls on governments to strengthen their climate targets by the end of 2022, putting pressure on big emitters.

COP26 president Alok Sharma says he expects "near final texts" of an agreement to be published overnight.

He will then convene "all groups, parties and observers again at 11am tomorrow in plenary to hear views".

Sharma also says the intention remains for the conference to close at the end of Friday.

We will be hearing from the prime minister at the summit later this afternoon.

Campaigners and experts have been urging Boris Johnson to do more to encourage countries at COP26 to take action on combating climate change.

On his train journey to Glasgow, he recorded a video in which he talked of the "significant progress" that had been made so far at the talks.

But in the clip posted on social media, he acknowledged "there's still a long way to go".

Johnson also highlighted the passing of the government's environment bill, as well as the UK commitment to cut CO2 emissions by 78% on 1990 levels by 2035

He said the UK was leading the world and was hoping other countries would follow "and keep up the pace".

As we've been reporting, the conference is focusing on transport today.

Promoting green mobility is a key part of the EU’s European Green Deal plan for a climate-neutral continent by 2050.

To get there, transport emissions need to be cut by 90%. Many cities are already making permanent the environmental measures they added during coronavirus lockdowns.

“Cycling is a very easy way to cut your CO2 emissions and help the fight against the climate crisis,” says EU Commission vice-president Frans Timmermans.

From Berlin to Budapest, Paris to Milan, extra and extended bike lanes have been built to help support the cycling boom. Reduced speed limits have been introduced in Amsterdam and Brussels. In the past year, 14 out of 27 EU countries have had at least one tax incentive or purchase-premium scheme to boost cycling.

But not everyone feels the current changes and plans go far enough. The European Cyclists’ Federation and 63 pro-cycling groups from all over the world have signed an open letter urging all governments at COP26 to commit to drastically increasing global cycling levels to dramatically cut transport carbon emissions.

Stronger plans and pledges need to emerge from COP26, according to John Ashton, the former UK climate envoy.

Speaking to the BBC, he says: "The aim of the exercise is to keep climate change within 1.5 degrees and the pledges and plans that are on the table... don't do that. They fall well short of it."

He adds: "If we want to come out of this summit and claim it was a success, we either have to get more ambitious... or we need to explain credibly and clearly with urgency what we are going to do to close the gap."

Mr Ashton says the summit has to "build on the fact that public are now way ahead of governments in the levels and ambitions they have on climate change - they want this problem fixed".

The draft agreement released today has garnered a mixed response, with many saying it does not go far enough.

But Lord Adair Turner, chairman of the Energy Transitions Commission, an industry group committed to achieving net-zero emissions, has voiced his support.

Speaking to BBC News, he said it was a "very good draft" because it says that nationally determined contributions (NDCs) - what countries commit to - need to be strengthened.

"This is exactly what we need to come out of this COP," he said.

The agreement - if it survives the negotiation process, and countries sign up to it - would mark a "significant step forward", he added.

Brazil say draft is tough on emissions but weak on fundingpublished at 14:45 Greenwich Mean Time 10 November 2021

Brazilian negotiators tell me the draft deal “goes in the right direction”, in the parts that mention the phasing-out of coal, cuts to fossil fuel subsidies and mechanisms to review targets.

But they say that more detail and clarity is needed to ensure accountability of financial contributions from developed countries to developing countries.

Brazil is pushing for the creation of a permanent committee to monitor how much money is being given by those developed nations.

For Brazil, the text is seen as being “robust in mitigation” - that is, preventing or reducing greenhouse gas emissions.

However, the feeling is that it is weak when it comes to funding and adjusting to the current and future effects of climate change.

The negotiators also criticise the absence of the terms “energy” and “energy transition” in the text.
