text: Labour had few experienced lawyers in its ranks in Parliament and had experienced problems filling the positions of legal officers in its first government. Jowitt agreed, but resigned his seat and stood again as a candidate for the Labour Party. At the by-election in July 1929, Preston re-elected him with an increased majority. As was customary, Jowitt received a knighthood upon becoming attorney general. His work mainly concerned the drafting of government bills, particularly the reversal of the Trade Disputes and Trade Unions Act 1927.
  As was still the custom for the attorney general, he occasionally prosecuted in high-profile cases, notably Sidney Harry Fox, charged with murdering his mother by suffocating her and then setting fire to her hotel room. It was said that a single question from Jowitt ("Explain to me why you shut the door?") sealed Fox's fate since Fox could think of no convincing answer.
  Divided loyalties (1931–1939)
  When the Labour government split over the financial crisis in 1931, Jowitt was one of only a handful of Labour MPs to follow MacDonald into the National Government. He was uncomfortable in a coalition with the Conservatives but believed that the proposed spending cuts causing the split were necessary, and the coalition was necessary to force them through. Like others who joined the National Government, he was expelled from the Labour Party.
