Gun salutes will sound across London on Tuesday to mark the birth of the royal baby as the armed forces join in the celebrations.
The King's Troop Royal Horse Artillery and the Honourable Artillery Company will carry out the ceremonial royal salutes in honour of the new addition to the Royal Family.
Gun salutes are fired for the birth of every prince or princess, no matter where their place is in the line of succession, the Ministry of Defence said. The last royal salute for a birth was for Princess Eugenie in 1990.
The King's Troop Royal Horse Artillery, wearing full dress uniform, will ride past Buckingham Palace to Green Park where they will stage a 41-gun royal salute.
They will ride from their forward mounting base in Wellington Barracks into Green Park, where 71 horses will pull six First World War-era 13-pounder field guns into position for the royal salute at 2pm.
Each of the six guns will fire blank artillery rounds at 10-second intervals until 41 shots have been fired. The horses and riders will then collect the guns and escort them back to Wellington Barracks.
