Award-winning Getty Images photojournalist Chip Somodevilla is best known for covering US politics, especially during election season. Over the last two weeks he has been covering the UK general election through the prism of a Washington lens.

Somodevilla says: "Never in my 10 years of political coverage have I ever seen one person [Nicola Sturgeon] so patiently comply with request after request for a selfie. Today's appearances reminded me of a time in American politics that is long gone, a time when people were allowed to interact with national political leaders because they were citizens, and not because they paid tens of thousands of dollars to attend private dinners with them."
