Treaties negotiated with foreign powers create binding obligations on future generations that cannot be repealed in the way that domestic law can. As a consequence, the most rigorous process should be in place to scrutinise such treaties before they ever come to be ratified.

Labour believes that every trade deal should come before parliament for a full debate on the floor of the House of Commons, with a vote at the end of that debate.

MPs should be able to debate, amend and approve a mandate for the negotiation of any trade agreement before talks start, based on an independent impact assessment of what social, economic and environmental risks might be expected.

The Tories must stop focusing on their ideological obsession with a hard Brexit and their internal party divisions and start focusing on what is best for our country and our economy. Their absurd proposal that the U.K. should become the E.U.'s tariff collector is neither practical nor palatable across the Channel.

Normally I am clear beforehand about which single proposal in a binary choice I am going to vote for.

It appears that President Trump wishes to disrupt the global multilateral trading system as much as possible.

World leaders need to work together through the rules-based system of the WTO to tackle unfair practices, including the widespread dumping of steel on world markets at less than market price.

Dictators have an old trick to assess the strength of their opposition: they say something patently untrue, and then look to see who mindlessly repeats it. Those who do, they recognise as their true supporters.

The Tories' favoured trade deals post-Brexit are likely to make regional inequality worse, by focusing on the best deal for the City of London at the expense of smaller firms across the country.

A Brexit that works for Britain needs to work for small businesses and must ensure that our future trade deals don't just work for big business.

Science tells us we need to keep the majority of fossil fuels in the ground, and that we must urgently invest in renewable energy, and other alternative industries. Doing so would create millions of jobs, ensure a fair transition for fossil fuel workers into new industries, and avert the most catastrophic climate breakdown.

The future can be just and green - not corruption-mired and polluted.

We must commit to a positive programme of ocean recovery to combat the effects of climate breakdown, and boost our oceans' capacity to tackle climate change.

Thanks to David Attenborough and 'Blue Planet 2,' we've become aware of the damage to our oceans from plastic pollution. We now know to use textile shopping bags instead of plastic, reuse coffee-cups and refuse polystyrene ones, and avoid plastic straws when ordering a drink at the bar.

As the oceans get hotter, corals also become heat-stressed and expel the algae that live on their skeletons, resulting in coral bleaching events that can wipe out entire reefs. This destroys the habitat that supports a quarter of all marine life.

As we pump greenhouse gases into our atmosphere, the ocean absorbs carbon dioxide, making the seawater acidic and hostile for shellfish and corals.

Acidisation isn't benign - like fracking, it can pose risks to groundwater sources, and runs counter to the urgency with which we must shift away from fossil fuels.

Doing nothing to stop national parks being drilled for oil isn't what climate leadership looks like.

We recognise the link between environmental failure and social injustice. When the energy sector is privatised and deregulated, it not only tends to pollute more, it also charges the poorest more per unit!

We recognise the need for government to provide a clear and stable regulatory framework so as to release the investment power of business in order to deliver progressive public policy.

Climate change must be approached as an opportunity to transition our economy to a zero carbon future. Business understands this even when governments don't.

The most important thing to understand about Trump's withdrawal from the Paris Climate Change agreement is, whilst it undeniably damages the rest of the world, it does most damage to America itself.

The direct risks from climate change are obvious: as changing weather patterns cause extremes of flood and drought, hurricanes and typhoons. These damage the physical infrastructure of buildings and bridges roads and railways. They are violent and disruptive.

In order to properly measure the impacts of climate change on our Financial system they must first be identified and disclosed.
