The crowd erupted as an ambulance drove past a march of striking workers on Hope Street.
Its crew punched the air, clapped their hands, honked the horn and sounded the siren as the protesters returned the gesture from a sea of flags fluttering ever stronger as the roar of the crowd grew before the ambulance descended Mount Pleasant.
Between the city's two cathedrals, workers shared a moment of solidarity on a day 500,000 people went on strike across the UK. In Liverpool, roughly 3,000 teachers, railway workers, civil servants and university staff represented by at least six different unions left their pickets across the city to gather in the shadow of the Metropolitan Cathedral and march through the city on Wednesday.
