The hon. Lady reminds this House that this is such a tragic loss of life. She talked of those lives cut short in London. There are colleagues here representing seats across the country where we have, sadly, lost lives. She is absolutely right to highlight this but, as I said, I really wish standing here that there was just one simple answer—just one single thing that could be done. We require action across multiple fronts and the best way to achieve that is for all of us to recognise that and to work together to deliver it.
