The UK Supreme Court has upheld the government's decision to deny Prince Harry automatic police security while in the UK.

The court ruled that the case-by-case security provision method was lawful and justified.

Prince Harry, who has ceased to be a full-time working royal, is now responsible for a legal bill estimated at £1 million due to the lawsuit's outcome.

The duke intends to challenge the Supreme Court's decision through an appeal.

Separately, the UK government is increasing security funding for lawmakers and officials in response to safety concerns.

New incidents of aggressive paparazzi in New York City have prompted the NYPD to review and adjust security arrangements for Prince Harry and Meghan Markle's visits.
