Labour can never govern with Ed Milliband being unmarried

So Ed Milliband is head of Labour and he has children and a partner, who he refuses to marry.
Whoever governs the UK, does so on behalf of it's voters and the Queen.
The Queen is Head of the Protestant Church, the religion of the UK.
Religious laws state that partners should be married or are committing adultery.

So how can the Labour Party accept this and still want to govern the UK !!!
