A church in London has given an ancient custom a digital twist by replacing the farm tools of a traditional "Plough Monday" blessing with the laptops and smartphones of today's modern worker.

Plough Monday is said to date back to medieval times when on the first Monday after Twelfth Night farm  workers would bring their ploughs to church for a blessing.

The Rev Canon David Parrott of St Lawrence Jewry in the City of London said at the special service: "May our tongues be gentle, our e-mails be simple and our websites be accessible".

"By your blessing, may these phones and computers, symbols of all the technology and communication in our daily lives, be a reminder to us that you are a God who communicates with us and who speaks by your Word. Amen".
