formed up and led by the band, it marches across into the forecourt of Buckingham Palace. Once there, the new Guard advances toward the old guard in slow time and halts. The old guard presents arms, followed by the new guard presenting arms. The captains of the guards march towards each other for the handing over of the palace keys. The new reliefs are marched to the guardrooms of Buckingham Palace and St James's Palace where new sentries are posted.
