Jo Cox MP lived her life spreading her belief that we have more in common than that which divides us.
In that spirit, her family and friends are inviting people across the country to mark the anniversary of her murder by organising or attending a celebration in their community.
The Clapham event
will take place on Sunday, 18 June, which is also Father's Day. All you need to do to take part is to come along with picnic blankets, food to eat and - if you can spare it - some to share.
So please save the date, spread the word and join us.
P.S. We're looking for all kinds of entertainment (face painting, acoustic music, juggling, magic tricks, etc) so if you have something to offer, please let us know by posting to the timeline.
