After two Conservative councillors who had moved to Gloucestershire resigned, by-elections took place in Moor View and Plympton Chaddlewood, which were won by Labour and the Green Party respectively.

[5] Several Conservative councillors left their group to sit as independents, including the former council leader Ian Bowyer, after two of them were suspended by the group leader Nick Kelly for publishing a press release supporting a reduction in the speed limit on the A38 road through the city.

[13][14] Terri Beer resigned from the Conservative group to sit as an independent councillor in response to Bingley's election.

[17] Labour won Compton ward for the first time, with the winning candidate, Dylan Tippetts, becoming Plymouth's first trans councillor.

[21] He resigned from the group on 15 October, complaining that he had been deselected and accusing Bingley of a "vile, defamatory, and inaccurate outburst against me and fellow councillors".

The BBC journalist Ewan Murrie wrote that the Labour group would be "unlikely to call a no confidence vote before the May elections".

[39] Since 2017, the council had been preparing for regeneration work along Armada Way, a major commercial street in the city centre.

[42] A majority of responses to the consultation opposed the plan, but the council said that most opposition did not include a reason and that the numbers were increased by activism from Straw.

[43] The council leader Richard Bingley said that the public supported the scheme, saying it would make the road safer and provide better drainage.

[44] During the night of 14 March, contractors cut down 110 mature trees after Bingley signed an executive order to approve the work.

[45] Sixteen more had been planned to be cut down, but the work had to be stopped after a judge "granted an injunction against the tree felling" requested by Straw.

[48] Bingley said that there should be a public inquiry into the regeneration scheme, suggesting that Labour and Green Party politicians should share responsibility for decisions about it.

[50] On 22 March, the Independent Alliance and Green Party group both called for Bingley to resign, with the latter proposing a vote of no confidence.

The former Labour councillor Chaz Singh took on the role of acting leader of the Independent Alliance group while Kelly recovered.

[59] The Labour group leader Tudor Evans said that the Conservative administration felling trees in the city centre was not one of the issues raised most often by voters, who wre instead focused on the cost of living, particularly food and energy prices.

He said that a Labour council would increase the number of trees, wildflowers and greenery in the city centre alongside "economic diversification".

[58] The Conservative candidate and former councillor Andrea Johnson said that most voters who bring up the cost of living were grateful for government support rather than critical.

[61] A multilevel regression with poststratification model by the polling firm YouGov suggested that Labour were likely to get 42% of the vote, with the Conservatives on 32%, the Liberal Democrats and Greens on 7% each, and independents and minor parties on 11% together.

[62] The Times predicted further losses for the Conservatives, highlighting Labour's need to make gains in the city in the 2024 United Kingdom general election to be able to form a government.

[69] Evans said that he would prepare an action plan to support people struggling during the cost-of-living crisis and deliver on the promised priorities from his party's election campaign.

[70] A by-election in Efford and Lipson is due to be held on 12 June 2023 to fill the seat of Brian Vincent, a Labour councillor who died in April 2023.

[75] Later that month, the Labour councillor Sue McDonald announced her resignation for "family health reasons".
