MPs have been debating the impact of loneliness on communities.
It was something that Jo Cox had campaigned about when she held the Batley and Spen seat.
Labour's Rachel Reeves - who represents Leeds West - fought back tears as she paid tribute to the work of her former colleague.
She highlighted research which showed being on your own can be as bad as smoking or eating unhealthily.
There are an estimated 1.2 million people in the UK who have "chronic" loneliness, with links to poorer physical and mental health and increased use of GPs, hospitals and social services.
Loneliness is worse for us in terms of mortality than obesity is and being acutely lonely is as bad for your health as smoking 15 cigarettes a day.
