Boris Johnson is under fresh pressure from his own MPs over planning reforms which contributed to the Tories' embarrassing by-election defeat this week.
The PM is likely to face clashes with Conservative rebels who oppose the shake-up, after a Cabinet minister rejected their criticism in the wake of the Chesham and Amersham drubbing.
As the party questions why it lost the former stronghold to the Liberal Democrats, Justice Secretary Robert Buckland said the planning reforms were being "mischaracterised" when confronted with criticism from senior Conservative MPs including former prime minister Theresa May.
He insisted the Government is "obliged to listen" to voters' concerns but did not indicate ministers were considering a compromise on the plans, instead focusing on their "mischaracterisation" by opponents.
Labour will attempt to heap pressure on the Prime Minister over his proposals by calling on backbench rebels to support the opposition on Monday in a Commons vote calling for protections for communities to object to planning applications.
Mr Buckland was shown a leaflet used by the Lib Dems ahead of Thursday's by-election containing Mrs May's claims that the plans risk the "wrong homes being built in the wrong places" when appearing on The Andrew Marr Show on Sunday.
"Our policy very often was very frankly mischaracterised. At no time has this proposal been about suddenly indiscriminately bricking over the countryside," Mr Buckland said.
He was also asked about former environment secretary Theresa Villiers' suggestion that a "fairer distribution" of new homes is needed "rather than seeking to cram so many thousands more into the crowded South".
"I don't believe the policy's about that," Mr Buckland told Nick Robinson, who was presenting the BBC show.
"I don't agree with the characterisation that's been described."
Pressed if he agrees with Mrs May and Mrs Villiers, Mr Buckland said: "No I don't. I think the policy is absolutely right. What it's designed to try and do is make sure we get that balance across the country."
Labour's Opposition Day motion will not be binding on the Government but the Prime Minister would be under pressure to rethink his proposals if a significant number of Tories vote with Labour.
Shadow communities and local government secretary Steve Reed said: "Voters have shown Conservative MPs what they think of the developers' charter. Those MPs now have the chance to join Labour in voting to kill off these perverse reforms once and for all."
Two senior Tory rebels told the PA news agency that they would not be backing a Labour motion and doubted many Conservatives would support a vote in the name of the opposition.
However, a similar move in January did see six Conservatives back a Labour motion calling for the Government to maintain the £20 weekly rise in Universal Credit.
The Buckinghamshire constituency in the Chilterns had voted Tory since its creation in 1974 until Thursday, when the Lib Dems overturned a 16,000 majority to win by more than 8,000 votes.
Along with the HS2 rail line being built through the constituency, fears over building in the countryside were a major issue in the campaign.
With a target of building 300,000 new homes a year in England, ministers want to overhaul the planning system, arguing reforms would boost the building of high-quality, sustainable homes by streamlining the process and cutting red tape.
Critics warn the plans will undermine local democracy by removing the public's right to be heard in person and would strip elected planning committees of development decisions.
Tory former Cabinet minister Damian Green warned the Tories could become "disconnected" from voters if the party fails to listen following the by-election defeat by improving the "thin" level of oversight in the plans.
"People want some form of local control... people don't want to feel that they're going to have developments dumped on green fields near them when they and their local representatives have had no say over it," the MP for Ashford, in Kent, told BBC Radio 4's Today programme.
Peter Fleet, the Tory candidate beaten by Lib Dem Sarah Green in Chesham and Amersham, warned Mr Johnson that typical Tory voters who did not turn out to vote for the party want to hear more about "traditional Conservative values" and for him to "restore fiscal discipline at the earliest possible opportunity".
"They fear a return to a bloated public sector which stifles private enterprise and demands ever higher taxes," he wrote in The Sunday Telegraph.
"They very much like and respect Rishi Sunak. And they do not expect fretful Tory backbenchers to push the Chancellor into saying yes to every request for more and more public spending from the benches opposite."
