It seems that the Labour government has ambushed the opposition parties and stolen their policies. But why shouldn't the government take the best ideas from wherever they can find them? In fact they didn't just steal them, they "improved" them too, selecting £600k as the IHT threshold, as opposed to the Conservatives £1m limit, in order to save a claimed £2bn in tax while offering gains to the vast majority.
While Interactive Democracy still requires a party political system, government and parliament, it encourages the development of ideas for the common good: the notion of "I'll see your idea and raise it!" is fundamental to improvement and central to Interactive Democracy.
Please note: I have no alliance to any political party.
