(PREMIER) — Accomplished singers from the Sistine Chapel Choir in Vatican City and Her Majesty’s Chapel Royal Choir have sung together at Buckingham Palace in support of persecuted Christians of all denominations.

Birgitte, Her Royal Highness the Duchess of Gloucester, attended the concert within the ballroom of the royal residence in central London.

The event highlighted the work of Aid to the Church in Need (ACN), a Catholic charity supporting believers living under pressure for their faith around the world – particularly in the Middle East.
