MPs are able to begin their oath however they wish, and some made it clear that their allegiance is to the people:
Labour MP for Leeds East, Richard Burgon, took the affirmation in order to represent his constituents:"I, Richard Burgon, was elected by the people of Leeds East to represent the interests of the people of Leeds East, and therefore make the following affirmation to enable me to do that..."
In 2015 Richard began his oath with the following statement:"As someone that believes that the head of state should be elected I make this oath in order to serve my constituents..."
Today Labour MP for North West Durham, Laura Pidcock, took the affirmation to represent the interests of her constituents:"I, Laura Pidcock, was elected by the people of North West Durham to represent their interests, I therefore take this affirmation in order to do that…"
Labour MP for Derby North, Chris Williamson, called for an elected head of state before taking the oath:"Like my father before me, I believe in an elected head of state, so I take this oath in order to serve my constituents…"
Labour MP for Newport West, Paul Flynn, took the oath under protest:"As a republican by conviction, and under protest...I swear by almighty god that I will be faithful and bear true allegiance to her majesty…"
After taking the oath, Liberal Democrat MP for Oxford West and Abingdon, Layla Moran, tweeted:"Today I am sworn in as an MP. A great honour. I have the choice of pledging loyalty to God or the Queen. Would have much preferred 'The People’."
After taking the oath, Labour and Cooperative MP for Leeds North West, Alex Sobel, tweeted:"I have taken the affirmation and am officially an MP. It’s a shame there's no reference to serving your constituents which needs to be added."
Not all Brits are stupid. We're just collectively slow
