William Glynne Charles Gladstone (14 July 1885 – 13 April 1915) was a Liberal Party politician in the United Kingdom, and the last of four generations of Gladstones to sit in the House of Commons, the first being his great-grandfather Sir John Gladstone (1764–1851).^[1] His body was the last to be officially repatriated to the United Kingdom during the First World War.^[2]

Gladstone was born on 14 July 1885.^[3] His father, William Henry Gladstone (1840–1891), was the eldest son of the Liberal Prime Minister William Ewart Gladstone and his wife Catherine, and his mother was the Hon. Gertrude Gladstone, daughter of Charles Stuart, 12th Lord Blantyre. He inherited from his father the 18th-century Hawarden Castle which had belonged to the family of his grandmother's brother Sir Stephen Glynne, the 9th and last baronet.^[4]

He was educated at home before attending Eton and then New College, Oxford. He was president of the Oxford Union in 1907^[5] and graduated with a second class degree.^[6]

On 13 April 1915,^[12] he was killed in action near Laventie,^[13] three weeks after arriving in France.^[2] He was shot by a sniper.^[6] He was initially buried in France, but permission was granted by King George V for his body to be brought back to the United Kingdom.^[2] Nine days after his death,^[2] his body was disinterred and re-buried in the churchyard of St Deiniol's, Hawarden, Flintshire, Wales.^[14] Also commemorated on the gravestone is his cousin William Herbert Gladstone, MC, son of Stephen and Annie Gladstone, killed in action in 1918.

As a memorial, a rood was installed at St Deiniol's, Hawarden and a new theatre and wards at Chester Royal Infirmary. Gladstone is also commemorated on Panel 8 of the Parliamentary War Memorial in Westminster Hall, one of 22 MPs who died during the War to be named on that memorial.^[15][16] Gladstone is one of 19 MPs who fell in the war who are commemorated by heraldic shields in the Commons Chamber.^[17] A further act of commemoration came with the unveiling in 1932 of a manuscript-style illuminated book of remembrance for the House of Commons, which includes a short biographical account of the life and death of Gladstone.^[18][19]

After his death, the estate was purchased by an uncle Henry Gladstone, the third son (and seventh child) of William and Catherine.^[20] Herbert Gladstone, another uncle, wrote a memoir of him that was published in 1918.^[21]
