Catholic officials in England are seeking to place Cardinal Newman's remains more in a prominent location in anticipation of his beatification (the penultimate step in being recognized as a saint).
I know it sounds odd to move a body -- but it's not uncommon in the annals of the Church. It's a way to build greater knowledge of the saint among the Faithful.
In fact, here in NYC, the remains of Paulist Father Isaac Hecker were moved from a mausoleum under the Church of St. Paul the Apostle (which Hecker founded) into a large sarcophagus located upstairs in the church itself. Hecker's sainthood cause is in its early stages.
