Purely for practical reasons as I'm breastfeeding. I really, really want to go but in view of the division and anger tonight's vote in Parliament (and Brexit generally) has stirred up I wonder if it can actually stay peaceful. I don't want to be irresponsible about her safety and am genuinely interested to hear views. I don't live in London, it would be approx 4 hour return journey so it's not possible to leave her all day.
