The Syria vote was a triumph of parliamentary sovereignty

Votes such as last night's are no longer mere rubber stamps but a binding convention that can change the foreign policy of a government.

There are several significant angles to last night's Commons vote on Syria. Foreign policy experts look at Britain’s role in the world and our relationship with the United States; domestic politicos look through the prism of party politics, asking who came out better between Miliband and Cameron. Meanwhile, Syria continues to suffer and we can only now hope that inaction is the lesser of two evils.

But amid the fallout, easily obscured by the more obvious issues of the day, is a seismic shift in the British constitution, an evolution that has crept up quietly but which serves to empower Parliament and constrain the executive. 

While the Prime Minister officially retains the Royal Prerogative to declare war, it is clear that this power is now tempered by the convention that Parliament must vote on the matter beforehand.

Previous votes on Iraq and Libya, while contentious, saw the government of the day validated by the Commons. Before this it had been understood that the executive had a right and duty to declare war as it saw fit. The real test of this innovation was whether a government convinced of the need for military action would respect a vote that opposed it.

The fact that Cameron had to promise the House that it would have a second vote, the fact he has now changed course so dramatically – while retaining the right to declare war - shows that votes like this are not simply rubber stamps but have become a binding convention that can change the foreign policy of a government.

Ironically, by calling an unprecedented vote on Iraq, Tony Blair, the most presidential of prime ministers, set in place an innovation that created a precedent largely devolving 'war powers' from the executive to the legislature.

Frustrating for many, our uncodified constitution is nevertheless pragmatic and far from conventions being ignored (as many fear has increasingly happened) a new one that curtails government power has clearly entrenched itself.

In the Lords, former generals, admirals, defence secretaries and ambassadors urged caution, while the debate in the Commons was marked by many MPs speaking of their constituents’ concerns. Some cheap politicking (from both benches) aside, the standard of debate was high and the tone respectful.

Whether one agrees with the outcome or not, the vote was a reassertion of Parliamentary sovereignty – a message to the executive, but also to the United States, that in the United Kingdom it is with Parliament, not the Prime Minister, that ultimate power resides. Indeed, many MPs spoke of this as a retreat from British presidentialism and a return to the PM being primus inter pares.

It is now unthinkable that Cameron would disregard Parliament’s wishes. Likewise, his deference to the Commons and his claim to have listened further entrenches the precedent that any future Prime Minister would have to call a similar vote on military action.

In my view, reserve powers of Royal Prerogative should remain with the Executive in case a Prime Minster must act immediately before explaining himself or herself to the House. But it is now clear that any premeditated military action will rightly require the approval of Parliament.

The British constitution is something that has grown organically over the last thousand years. It has survived because it has evolved; its imperfections have been mitigated by its flexibility. This latest stage in its evolution has something to say of our present and of our past. It speaks to a country disillusioned with foreign interventions, war-weary and cautious of unknown consequences. But fundamentally it also reasserts an ancient British principle: Parliament is sovereign.

Air pollution: 5 steps to vanquishing an invisible killer

A new report looks at the economics of air pollution. 

110, 150, 520... These chilling statistics are the number of deaths attributable to particulate air pollution for the cities of Southampton, Nottingham and Birmingham in 2010 respectively. Or how about 40,000 - that is the total number of UK deaths per year that are attributable the combined effects of particulate matter (PM2.5) and Nitrogen Oxides (NOx).

This situation sucks, to say the very least. But while there are no dramatic images to stir up action, these deaths are preventable and we know their cause. Road traffic is the worst culprit. Traffic is responsible for 80 per cent of NOx on high pollution roads, with diesel engines contributing the bulk of the problem.

Now a new report by ResPublica has compiled a list of ways that city councils around the UK can help. The report argues that: “The onus is on cities to create plans that can meet the health and economic challenge within a short time-frame, and identify what they need from national government to do so.”

This is a diplomatic way of saying that current government action on the subject does not go far enough – and that cities must help prod them into gear. That includes poking holes in the government’s proposed plans for new “Clean Air Zones”.

Here are just five of the ways the report suggests letting the light in and the pollution out:

1. Clean up the draft Clean Air Zones framework

Last October, the government set out its draft plans for new Clean Air Zones in the UK’s five most polluted cities, Birmingham, Derby, Leeds, Nottingham and Southampton (excluding London - where other plans are afoot). These zones will charge “polluting” vehicles to enter and can be implemented with varying levels of intensity, with three options that include cars and one that does not.

But the report argues that there is still too much potential for polluters to play dirty with the rules. Car-charging zones must be mandatory for all cities that breach the current EU standards, the report argues (not just the suggested five). Otherwise national operators who own fleets of vehicles could simply relocate outdated buses or taxis to places where they don’t have to pay.  

Different vehicles should fall under the same rules, the report added. Otherwise, taking your car rather than the bus could suddenly seem like the cost-saving option.

2. Vouchers to vouch-safe the project’s success

The government is exploring a scrappage scheme for diesel cars, to help get the worst and oldest polluting vehicles off the road. But as the report points out, blanket scrappage could simply put a whole load of new fossil-fuel cars on the road.

Instead, ResPublica suggests using the revenue from the Clean Air Zone charges, plus hiked vehicle registration fees, to create “Pollution Reduction Vouchers”.

Low-income households with older cars, that would be liable to charging, could then use the vouchers to help secure alternative transport, buy a new and compliant car, or retrofit their existing vehicle with new technology.

3. Extend Vehicle Excise Duty

Vehicle Excise Duty is currently only tiered by how much CO2 pollution a car creates for the first year. After that it becomes a flat rate for all cars under £40,000. The report suggests changing this so that the most polluting vehicles for CO2, NOx and PM2.5 continue to pay higher rates throughout their life span.

For ClientEarth CEO James Thornton, changes to vehicle excise duty are key to moving people onto cleaner modes of transport: “We need a network of clean air zones to keep the most polluting diesel vehicles from the most polluted parts of our towns and cities and incentives such as a targeted scrappage scheme and changes to vehicle excise duty to move people onto cleaner modes of transport.”

4. Repurposed car parks

You would think city bosses would want less cars in the centre of town. But while less cars is good news for oxygen-breathers, it is bad news for city budgets reliant on parking charges. But using car parks to tap into new revenue from property development and joint ventures could help cities reverse this thinking.

5. Prioritise public awareness

Charge zones can be understandably unpopular. In 2008, a referendum in Manchester defeated the idea of congestion charging. So a big effort is needed to raise public awareness of the health crisis our roads have caused. Metro mayors should outline pollution plans in their manifestos, the report suggests. And cities can take advantage of their existing assets. For example in London there are plans to use electronics in the Underground to update travellers on the air pollution levels.

Change is already in the air. Southampton has used money from the Local Sustainable Travel Fund to run a successful messaging campaign. And in 2011 Nottingham City Council became the first city to implement a Workplace Parking levy – a scheme which has raised £35.3m to help extend its tram system, upgrade the station and purchase electric buses.

But many more “air necessities” are needed before we can forget about pollution’s worry and its strife.
