Andrew Mountbatten-Windsor and the loss of his dukedom

In November 2025 the King formally stripped his younger brother of his royal styles and titles.

The announcement stated that "The King has been pleased by Letters Patent under the Great Seal of the Realm dated 3 November, 2025, to declare that Andrew Mountbatten Windsor shall no longer be entitled to enjoy the style, title or attribute of 'Royal Highness' and the titular dignity of 'Prince'.

A straightforward sweep of the monarch's pen reduced Andrew to a commoner, but was the King's disgraced brother similarly divested of his Dukedom, Earldom and Barony?  The removal of a peerage requires an Act of Parliament, and cannot be achieved by royal authority alone.

We were told that Andrew Mountbatten Windsor had been formally removed from the official roll of the peerage in the House of Lords, marking the definitive stripping of his royal titles. Buckingham Palace confirmed that Andrew's dukedom was struck from the roll.

The Lord Chancellor and Justice Secretary, is responsible for maintaining the peerage roll and he received the order from the King to formalise the removal of the Duke from the Roll of the Peerage. This however, did not mean that Andrew's peerage has been stripped away and consigned to history.

Many peers, including other dukes, are not on the Roll, but all the same are legally peers of the realm.

The Roll of the Peerage is an officially compiled and maintained list, intended to contain the names of all living peers. Peers are enrolled in it in the following circumstances:

Hereditary Peers who have proved succession in accordance with the terms of the 2004 Royal Warrant.

Hereditary Peers who up to 1999 received a Writ of Summons.

Hereditary Peers who from 1999 have proved their succession in order to be eligible either for election to a vacant seat amongst the remaining 92 hereditary peers in a House of Lords 'by-election', or to vote in such a by-election.

The Roll comprises all those Peers who have proved succession to an English, Scottish, Irish, Great Britain or United Kingdom Peerage. In some cases the Peer's name appears against his junior title; it may then be cross-referenced elsewhere in the Roll if the Peer is customarily styled in a different or senior title. This arises for example where succession has been proved in a junior title for the purposes of sitting in the House of Lords.

Each entry on the Roll is headed with the style of the dignity (the nomen dignitatis), e.g. 'Abercorn'; with the body of the entry showing:

whether the dignity is hereditary or for life.

the class or rank of dignity, i.e. duke/duchess, marquess/marchioness, earl/countess, viscount/viscountess or baron/baroness, (lord/lady in the case of some Scottish titles).

the Peerage within which dignity was created, i.e. the Peerage of England, Scotland, Ireland, Great Britain or the United Kingdom.

the full style of the current holder of the dignity, including forenames, and indicating where applicable any senior title by which he or she is customarily known.

the surname of the present holder of the dignity.

Some Peers not currently on the roll include:-

Acton B; Airlie E; Allenby V; Allendale V; Amherst of Hackney B; Argyll D; Ashbrook V; Ashtown B; Atholl D; Auckland B; Baden-Powell B; Bagot B; Baldwin of Bewdley E; Bangor V; Basing B; Bath M; Beatty E; Berners B; Bessborough E; Blyth B; Bolingbroke and St John V; Bradbury B; Brassey of Apethorpe; Brownlow B; Buchan E; Buckmaster V; Burden B; Burton B; Bute M; Caldecote V; Carnock B; Carrick E; Castle Stewart E; Castlemaine B; Cavan E; Charlemont V; Chelmsford V; Chesham B; Churchill B; Churston B; Clanmorris B; Coleraine B; Congleton B; Conyngham M; Cornwallis B; Coventry E; Craven E; Croft B; Cullen of Ashbourne B; Dalhousie E; Darwen B; Davidson V; Decies B; Delamere B; Denham B; Denman B, De Ros B; De Villiers B; Dickinson B; Dilhorne V; Donerall V; Downe V; Ducie E; Dufferin & Clandeboye B; Dunrossil V; Dunsany B; Egremont B; Elphinstone L; Elton B; Ely M; Esher V; Essex E; Fermoy B; ffrench B; Fitzwalter B; Forbes L; Forester B; Glendevon B; Gort V; Gowrie E; Granville E; Graves B; Grey E; Hambledon V; Harding of Petherton B; Harewood E; Harris B; Harvey of Tasburgh B; Hatherton B; Headfort M; Home E; Howard of Penrith B; Howick of Glendale B; Huntingfield B; Ilchester E; Inchiquin B; Inverforth B;Kenswood B; Kenyon B; Keyes B; Kilmaine B; Kingsale B; Kingston E; Langford B; Layton B; Leigh B; Lifford V; Lincoln E; Lisle B; Londonderry M; Long V; Longford E; Lonsdale E; Louth B; Lucas of Chilworth B; Luke B; Lyvedon B; MacAndrew B; Macdonald B; Malmesbury E; Malvern V; Manchester D; Manton B; Marchamley B; McGowan B; Massy B; May B; Mayo E; Merivale B; Methven B; Mexborough E; Milne B; Milverton B; Molesworth V; Monck V; Moncreiff B; Montagu of Beaulieu B; Monteagle of Brandon B; Moray E; Mottistone B; Mount Edgcumbe E; Muskerry B; Newburgh E; Norbury E; Orkney E; Palmer B; Piercy B; Plymouth E[ Raglan E; Ranfurly E; Rathconnell B; Ravensworth B; Rea B; Reith B; Rendlesham B; Rennell B; Ritchie of Dundee B; Riverdale B; Rochester B; Rodney B; Rootes B; Rosse E; Rothes E; Runciman of Doxford V; Sackville B; St Vincent V; Samuel V; Sanderson of Ayot B; Sandford B; Scarsdale V; Selby V; Selkirk E; Shannon E; Sherfield B; Sidmouth V; Sinclair of Cleve B; Sinclair L; Sinha B; Southwell V; Stamp B; Strabolgi B; Strathcona and Mount Royal B; Stuart of Findhorn V; Sudeley B; Sutherland E; Swinton E; Talbot of Malahide B; Tankerville E; Tedder B; Tenby V; Tennyson B; Teviot B; Teynham B; Thomson of Fleet B; Trimlestown B; Tryon B; Tweedsmuir B; Valentia V; Wakehurst B; Wardington B; Waterford M; Westbury B; Westwood B; Wharncliffe E; Winchester M; Winterton E; Wolverton B; Wraxall B.

All the above are peers regardless of their failure to appear on the Roll. They include Dukes, cousins of the King and Prince of Wales (Harewood, Fermoy, Elphinstone), and the Earl of Dalhousie, who attended the Coronation of King Charles and Queen Camilla. 

So it's quite clear that Andrew's removal from the Roll was done to deceive and bamboozle the public into thinking that the King's brother is no longer Baron Killyleagh, Earl of Inverness or Duke of York, when in fact he is and will be until his death, or until an Act of Parliament is brought before Parliament.
