Commander Robert Tatton Bower (9 June 1894 – 5 July 1975) was a Royal Navy officer and a Conservative Party politician in the United Kingdom.
At the 1931 general election he was elected as Member of Parliament (MP) for Cleveland. He was re-elected in 1935, and held the seat until his defeat at the 1945 general election by the Labour Party candidate George Willey.
On 4 April 1938, Bower was involved in a House of Commons incident when he interrupted Jewish Labour MP Emanuel Shinwell, telling him to "go back to Poland". Shinwell walked across the floor of the House and struck Bower in the face, before turning to the Speaker, apologising and walking out of the chamber to calls from MPs of "Get out! Get Out!". Bower, who on being struck had merely "folded his arms and stared" Shinwell down, also then apologised to the Speaker. No disciplinary action was taken against either MP.
Although the open-handed blow from Shinwell was initially viewed as a "slap in the face", it struck Bower on the ear, resulting in internal bleeding between the layers of the left eardrum which was discovered four days later; a blood clot formed, causing the eardrum to burst. According to a report in Time magazine, Bower was described to be in "serious condition".
The context of this violent confrontation was a series of questions being put by Labour MPs to the Foreign Office minister R.A. Butler, challenging the government's apparent recognition of the Duke of Alba as a diplomatic representative of General Franco's nationalist forces, who were then in the midst of a civil war against Spain's Republican government. Shinwell had described Butler's answers as "humbug" and "hypocrisy" and was being reprimanded by the Speaker for unparliamentary language at the moment Bower made his own intervention. The Speaker, Capt. Edward Fitzroy, took the view that: "Both were so thoroughly disorderly, that I propose to ignore them if the hon. Members will apologise."
