A review of the security around Buckingham Palace has been launched after a break-in earlier this week.
A man was arrested on suspicion of burglary, trespass and criminal damage after he managed to scale a fence and enter the Queen's home on Monday night.
A second man was arrested outside the palace on suspicion of conspiracy to commit burglary.
