But the reason that we keep circling back to Heathrow is not just because it is the right technical solution. But because it is the only politically deliverable solution. No other UK airport offers value to every nation and region of the UK. Which, incidentally, is also why it is the only UK airport which is full - and it has been for a decade now.
As we enter 2016, it is clear that the centre of gravity of the airport expansion debate has changed. The momentum is now with Gatwick as people increasingly recognise it is the only deliverable option for the country. The choice is clear. Groundhog Day with illegal expansion at Heathrow and Britain losing out again or guaranteed growth at Gatwick as we choose to be the builders and see Britain reaping the benefits. The answer is obvious.
Thursday's speech from George Osborne is nothing short of astounding. After five and a half years in charge of the UK's economy he's reaching for excuses to explain his own failure. And while he is right to warn how what is happening in China and the rest of the world could affect Britain, the truth is that he's been far too late to wake up to this threat... It is too little, too late for George Osborne to warn about the risks to our economic recovery, including those coming from China. Now is not the time for him to line up excuses for his own failure - if there is a cocktail of risks lined up for the British economy, it's one Osborne has helped to mix.
Speaking in Cardiff recently, George Osborne warned that the UK faces a 'dangerous cocktail' of economic risks, pinning the blame on external forces such as China's slowing economy, for example. This is in stark contrast to the upbeat tone the Chancellor adopted during his Autumn Statement where you'd be forgiven for thinking the economy was thriving under the Conservatives.
My forecast is by the end of this Parliament there will be a lower percentage of homes that are owner occupied, there will be fewer social rented properties, there will be more insecurity and pressure on family budgets and we won't have built the million homes the Prime Minister promised. We should all be very worried.
Everyone deserves a home and a chance, but too many people my age in Scotland are either living at home with their parents or stuck in expensive rents unable to get that first foot on the property ladder. Home ownership is a big ambition for hundreds of thousands of Scots, but for too many people my age it remains an ambition rather than a reality.
This situation cannot and should not go on. Our railways are a public service, enabling people to get to work and linking families and friends who are separated by long distances. They can, and should, be the pathways to our business success and our engagement in leisure. Instead, they are overpriced, but underfunded. Overcrowded, but understaffed. Driven by profit, not by what is best for passengers. But there is an alternative.
I know from my own experience that universities and higher education transform the lives of individuals and shape our society for the better. In addition, with 130 higher education institutions in England, and revenues of £23.3 billion, 262,700 members of staff and two million students, universities are also powerhouses for economic growth in their own right.
It would be dangerous to presume that everything is now just fine with our banking system. It is a huge risk to assume that it's safe to return to 'business as usual'. Politicians who believe that all we need to is to return to 'letting the bankers get on with it' may come to regret taking this view. But with memories of the 2008 banking crisis fading in some quarters, it seems that the Conservative Government thinks it can start to undo that good and necessary work.
The Conservatives are upbeat, but if Osborne takes over they may find they have a leader who simply cannot appeal to voters as Cameron does. He still has several years to turn this around this, but right now it seems the next election may not be a foregone conclusion, after all.
Successful economies today have governments prepared to take a strategic approach to how development takes place. The old idea that simply exposing new industries to the full blast of competition will promote their development is increasingly discredited... But the Tories are stuck in the past, and ducking the challenge. In November, the UK became the only G7 country to increase fossil fuel subsidies. We are paying out £6billion a year, almost twice the financial support we provide renewable energy providers - which we are now continuing to cut. After the deal struck in Paris over the weekend, the shift to a low-carbon economy is inevitable. The government should be supporting this transition, not hampering it.
You've probably heard a lot of rhetoric from the Tories about this supposedly "high-wage economy" they're creating. If you have, it might surprise you to hear that there are almost a quarter of a million working people in the UK getting paid less than the legal minimum to which they are entitled. Sports Direct may be just the tip of the iceberg.
Today's annual Family Spending release from the Office for National Statistics contains a wealth of useful information - and the ONS has done a good job of presenting much of that data. Below we set out the Resolution Foundation's five key charts that explain just who spent what in 2014.
In London more than a third of our trips start or end within 200 metres of a tube stop - helping complement today's public transportation infrastructure. And more than four in ten Uber journeys are now in energy efficient hybrid cars that produce less pollution... Over time this could become a real game-changer for a city where a million people still drive to work each day with nobody else in the car.
Being in Europe makes Britain stronger in international trade talks. By being part of the world's largest market, standing with 500 million people, Britain is a more important trade partner for countries around the world than we would be on our own. This has been demonstrated vividly today with the signing of a new free trade agreement between the EU and Vietnam.
Employment rights are ultimately of benefit to everyone but the fee regime not only undermines those rights but actively encourages rogue employers to flout the law and I say it should be scrapped.
