Andrew dealt humiliating new blow from King Charles, claims Channel 5 documentary

Andrew Mountbatten Windsor could soon be left with the brutal new reality of relying solely on his £20,000-a-year naval pension as moves to strip him of his remaining titles and force him out of Royal Lodge ramp up yet again.

In a clip from Saturday's Channel 5 documentary, The Battle for Royal Lodge: Andrew vs the People, the programme points out that Andrew's naval pension is his "only known source of income". It is dwarfed by the eye-watering cost of keeping him protected.

Daily Mirror columnist Kevin Maguire does not hold back, saying: "The costs of his security alone are put at £3million a year. Where does that money come from?" Airing on Saturday at 8.55pm, the documentary dives headfirst into the increasingly tense saga surrounding Andrew's longstanding home, Royal Lodge.

Andrew, unlike other members of the Royal Family, did not choose to go to university but opted for a military career in the Royal Navy. In 1982, he joined his first frontline unit, 820 Naval Air Squadron, serving on HMS Invincible. The British aircraft carrier soon joined the task force that was sent to the Falkland Islands.

He continued to move up the ranks, becoming a lieutenant commander in 1992 and, from 1993 to 1994, commanded the minehunter HMS Cottesmore. In 1998, the then-prince was promoted to the rank of commander and joined the Diplomacy section. In 2001, he was released from the active list of the Navy with the rank of honorary captain.

Since then, the former Duke of York is now at the centre of a national storm, and the historic Windsor estate has become a symbol of his fall from grace. He has until the end of January to leave Royal Lodge, it is understood, despite being ordered to vacate by the King this week.

Charles also announced he is to strip all remaining titles from his brother - including prince - and will evict him from the 30-room mansion on the Windsor estate.

For more than two years, Andrew has remained secluded inside the lavish 30-room mansion as public anger intensifies. He is said to be relocating to an undisclosed property on the Sandringham estate in Norfolk.

Elsewhere, the programme shared the incredible history of the estate itself, a place deeply woven into the fabric of royal life. It was once the childhood haven of the future Queen Elizabeth and Princess Margaret, who spent hours playing in their miniature Welsh thatched house, complete with its own tiny kitchen.

It is where the Queen Mother hosted her legendary parties, conga lines and all, spilling out into the gardens.
