One of the most fascinating stats coming out of that period is that, with the Lib Dems having only 9% of the MPs in Parliament, Clegg still delivered 70% of the Lib Dem manifesto including all four of the 'priority' policies promoted on the front cover of the manifesto. They also achieved other good things that weren't even in the manifesto, like Lynne Featherstone's same-sex marriage legislation.

Cameron by contrast, with 47% of the MPs, failed to deliver many of his signature manifesto promises such as abolishing the Human Rights Act, reducing net immigration to the tens of thousands, introducing the Snoopers Charter, etc.

Objectively, Clegg's 57 MPs were a pretty effective parliamentary unit, and yet it's fascinating how the Tory media helped shape a narrative that it was the Lib Dems who were facilitating a Tory government and not the other way around. I remember in 2010 after the coalition agreement was first published, a lot of the discussion was about how successful the Lib Dems had been - it's interesting how that perception evolved after five years of the media hammering voters with a different message.
