Despite starting this season on the sport. Despite starting this season on 35 points, such as the strength of saracens squad they have continued to win and had looked set to avoid relegation this season, andi set to avoid relegation this season, and i think that partly explains the anger and resentment felt by their rivals, the clubs we met earlier this week who met earlier this week and told the premiership in no Uncertain Terms something had to be done. There will be very serious ramifications now for the league, whose credibility is on the line, for the club itself here who face the risk of losing valuable sponsorship, of course, and fans as well, and perhaps mostly for their players, who form the core, lets remember, of the england team. Just a few months ago several of them we re a few months ago several of them were playing in the World Cup Final itself and now they face the real prospect of playing in the second tier championship. Will they leave . Second tier championship. Will they leave . Will they take pay cuts . Will they go on loan . Will they stick it out . This is a time of course when they will want themselves in the shop window for lions selection. The rfu tried to reassure them and say they would still have the chance of selection for england even if they are not playing in the premiership, but this must certainly be a very unsettling time indeed and certainly an unprecedented period for english by an unprecedented period for english rugby now.

You are lying even if you are standing beside iranian people it is just so you can stab them with your poison daggers. Death to america, death to england, chanted the crowd.

A number of british cities are aiming to go completely Carbon Neutral by 2030, removing as much Carbon Dioxide from the atmosphere as they put in to it in a bid to tackle Climate Change. Glasgow, which is hosting a major un Climate Change summit later this year, is one of them. Its promising to achieve the ambition by radically cutting emissions and planting enough trees to absorb the carbon in any remaining fumes. 0ur science editor David Shukman reports from glasgow, in the latest part of the bbcs our planet matters series. From a proud history as an industrial powerhouse, glasgow now wants a future that is Carbon Neutral. No easy task in a city that depends on fossilfuels. Its motorways encourage commuters to use their cars. The Councils First move is with its gritting lorries. They run on diesel and are now being adapted to use cleaner hydrogen as well. They are as clean as possible. Just one step, says the councillor in charge, anna richardson, of many needed in the next ten years. We need to work as quickly as we can to decarbonise this city, as do all cities across the world. A 2030 target is hugely challenging, certainly. And it is going to mean everybody has to work hard to achieve that. But in your heart of hearts, do you think you could ever make it . I think we need to give it our absolute best shot. The biggest challenge in glasgow is that most people live in flats, many of them badly insulated, and nearly all heated by gas. In this social housing scheme, an old heating system is being removed to make way for a greener alternative. Its gone down well. New pumps draw warmth from the air. By contrast, another project on one of the poorest estates involved building this miniature power station. Tenants we met described their shock at their bills, which went up by different amounts. Worry, panic, anxiety. Whether im gonna be able to afford it when the bill hits the mat. Yeah, and anxiety to the point of illness. The scheme was imposed on tenants. Now, to a certain extent, that blindsided us. James and nick, in these tower blocks, are among thousands of tenants in this particular scheme and Cube Housing Association and sse, which run it, told us they are committed to Greener Energy and to tackling fuel poverty. According to chris stark, the uk governments independent climate adviser, it is vital that everyones views are heard. There is a huge risk in foisting upon People Solutions that have not had a full process of public consent behind that, behind them. And that is the bit that we havent done yet. Already, more and more electricity, for glasgow and the rest of the country is becoming cleaner. Here on the edge of the city, there are lands to expand this wind farm and to fit solar panels, but getting to zero carbon power is still a big struggle. As things stand, it is hard to see how glasgow, or any major city, could possibly be Carbon Neutral in as little as ten years. But the council says it wants to send a signal that at least its trying. And this comes at an important time. Because an International Summit on Climate Change is due to take place here in november so the world will be watching what the city does.
