How has the UK constitution been challenged since 2010?

How does the House of Commons respond when there is a challenge to Britain’s uncodified constitution? First we look at the prospect of Scottish Independence in September 2014. With the real chance of Scottish people voting to leave the United Kingdom, the way that the House of Commons functions might have to change. Politicians and officials throughout Westminster brace themselves for one of the biggest constitutional shifts the country has seen. The next example is a new law proposed by the government called the ‘Recall Bill’. It allows for MPs to be sacked by their constituents for serious wrongdoing. Conservative MP Zac Goldsmith thinks it doesn’t go far enough and we follow him as he tries to get enough support to challenge the government. What do his proposals mean for democracy? Does it give voters more direct influence on their MP? Or does it make MPs vulnerable to business and lobbying interests? We follow the story right up to the crucial vote in the House of Commons.
