The UK government is democratic on paper, sure. But in reality, does anyone know who their MP is? [0]
Five year terms? [1]
Total lack of responsiveness [2]
lack of real democratic accountability [3]
Sure, it looks democratic, but in reality it's not.[4] Particularly when the UK parliament doesn't even initiate (propose) legislation: ministers are appointed by the government, and are not elected to their position. And civil servants write the legislation before it goes to parliament.
[0] In 2013, 3/4 people could not name their MP. See https://www.bbc.co.uk/news/uk-politics-22555659
[1] Five years unless there is a supermajority or the loss of a no confidence vote. https://en.wikipedia.org/wiki/Fixed-term_Parliaments_Act_201...
[2] Numerous examples of this: https://www.mirror.co.uk/news/uk-news/how-responsive-your-mp... https://www.writetothem.com/stats/2015/mps
[3] There is an ability to recall MPs, but they need to have breached the parliamentary code bad enough to be suspended from sitting for a number of days or engaged in criminal behaviour and been duly sentenced. The current UK government is actively trying to strip people of voting rights who do not have the money for suitable photo ID (minimum £34)
[4] The UK's first-past-the-post electoral system means that the majority of votes do not matter.
