In this situation, in 1921, the Poplar Labour councillors decided to act to relieve the burden and to make a political protest by refusing to collect the rates on behalf of the
London County Council and other Metropolitan bodies. Key himself, as Chairman of the Public Health Committee, moved a resolution to refer the estimates back to delete the contribution to the LCC. Poplar had a legal duty to collect the rates, and the LCC obtained a judgment requiring payment. Key argued to continue the protest, because the LCC and government had failed to fund promised schemes in the borough. To enforce payment, the LCC and Metropolitan Asylums Board issued
writs against 30 Poplar councillors and
Aldermen; however, somewhat inexplicably, Key was not among those proceeded against. The 30 were committed to prison, while Key was made Deputy Mayor to act in the absence of the Mayor (
Sam March) who was to go to jail. He was a key organiser of the successful campaign to get the councillors released, and subsequently wrote pamphlets telling the history of the campaign. The rates strike secured a more effective system of easing the burden of LCC rates on poorer boroughs and making borough rates produce the same revenue for councils. ==Municipal service==
