Jestyn Philipps, 2nd Viscount St Davids

Jestyn Reginald Austin Plantagenet Philipps, 2nd Viscount St Davids Bt, (19 February 1917 – 10 June 1991) was a British peer, the only surviving son of John Philipps, 1st Viscount St Davids, and his second wife, Elizabeth Philipps, Viscountess St Davids (née Abney-Hastings).

While sitting the House of Lords, St Davids accepted the Labour Whip, although he later described himself as a convert to Thatcherism.

While serving in the Lords, St Davids opposed restriction on immigration.

He is also notable for being the first person to raise climate change in the houses of parliament, in 1969, over a decade before it was next mentioned:[2] "My Lords, can my noble friend say whether he and British Railways have taken account of the fact that what were abnormal temperatures last summer may not be abnormal if we continue to discharge carbon dioxide into the air by the burning of various fossil carbons, so increasing the greenhouse effect?

"[3] St Davids founded a 'pirate club' on the Regent's Canal in Camden Town, north London, which was designed to give local children a chance to spend time on boats.
