It was information overload from Marks & Spencer last week as it fired off a missive about the debut of its sparkly new depot.

Amid such fascinating snippets as how many Wembley pitches you could fit inside it (12) and how many miles' walk the perimeter is (just the one, a bit disappointingly), was the revelation that it would take "approximately 140 billion Percy Pigs" to fill the warehouse.

Sadly we have no idea how many Penny Pigs, Percy Piglets or Reversy Percys that equates to.
