It is a heartening and deeply spiritual experience to walk through the City's streets, singing hymns and reciting the Rosary and affirming one's Catholic faith.
Motorists stuck in the traffic will look at you as if they would like to see you re-routed via Tyburn Tree, but, no matter. They will only be delayed by a few minutes, say a prayer in response to their glaring looks.
The march leaves Westminster Cathedral at c. 1.45pm and heads off to the London Oratory where Mass and Benediction are normally offered.
And this year the march will be led by none other than the
Rt Reverend Monsignor Keith Newton, Protonotary Apostolic and Ordinary of the Ordinariate of Our Lady of Walsingham.
So, dust off your zimmer frames and get cracking!
