Conservative party leader Kemi Badenoch has promised to abolish stamp duty if the Conservatives win the next election as she closed the party conference.
Having focused on borders in her opening address, Ms Badenoch used her leader's speech to set out her vision of a country where the state "does less but does it better" and "profit is not a dirty word".
She pledged to impose a "golden rule" on her budget plans, spending only half of any savings made through spending cuts, with the rest going to reduce the deficit.
And she said she would cut student numbers, saving £3 billion that would then be spent on doubling the apprenticeship budget.
But in the final passages of her speech, she went further, committing to free up the housing market by abolishing stamp duty on people's primary homes.
She described stamp duty as a "bad tax".
"We must free up our housing market, because a society where no one can afford to buy or move is a society where social mobility is dead," she said.
Stamp duty land tax brought in an estimated £13.9 billion in the last financial year, but a large proportion of this is from additional homes and other buildings.
The Institute for Fiscal Studies (IFS) has estimated that abolishing stamp duty on primary residences will cost around £4.5 billion.
But, claiming that the Chancellor Rachel Reeves was planning a significant increase in stamp duty, the Conservatives said they had "cautiously" estimated that the policy would cost £9 billion.
'Sticking to golden rule'
Ms Badenoch insisted she could meet this promise while sticking to her new "golden rule", saying this was the "fiscally prudent" thing to do.
Her address brought to a close a conference that had been overshadowed by questions about her leadership and the threat from Reform UK.
The day before her speech, Nigel Farage's party announced 20 councillors had defected from the Tories, while a poll published by More in Common showed the Conservatives continue to languish in third place.
But the major defection that some in the party feared would take place this morning did not come, while Ms Badenoch attacked her opponents, vowing to reverse Labour policies and accusing Prime Minister Keir Starmer, Nigel Farage, Jeremy Corbyn and Sir Ed Davey of "shaking the same magic money tree".
Although she dismissed Reform as promising "free beer tomorrow", Ms Badenoch reserved most of her attacks for Labour, pledging to reverse a swathe of policies introduced by the new government.
Pledge to reverse government policies
These included abolishing VAT on private schools, reversing changes to inheritance tax for farms and scrapping the carbon tax.
Along with other spending promises made during the conference, the Conservatives estimated that these would cost a total of €21.1 billion, compared with €47 billion of savings shadow chancellor Sir Mel Stride said he had identified in his own conference speech on Monday.
In an apparent response to reports that attendance at this year's conference had declined, leaving swathes of the exhibition hall in Manchester empty, she said the Conservatives were "fizzing with ideas".
She insisted that the Tories were the only ones who could "meet the test of our generation", she thanked members for "standing by" the party.
Earlier, Tory chairman Kevin Hollinrake said he expected the announcements from the party conference would "move the needle in terms of the polls".
He said: "I think those messages have been very well received this week by our members, very optimistic view of where we are today from our members and indeed the future.
"So yeah, we expect things to improve in terms of our political fortunes."
Controversy over shadow justice's racial remarks
This year's Conservative party conference made headlines for its low attendance numbers, with images of empty seats in the auditorium during speeches from Shadow Cabinet members.
Ahead of his speech yesterday, the party's Shadow Justice Secretary Robert Jenrick sparked controversy after he was heard complaining that he "didn't see another white face" during a 90-minute visit to an area of Birmingham.
The recording was obtained by the Guardian.
Mr Jenrick has defended his comments, insisting he "won't shy away" from issues of integration.
However, a former Tory mayor of Birmingham, Andy Street, said Mr Jenrick was wrong.
In his speech yesterday, Mr Jenrick also criticised British Attorney General Richard Hermer for representing former Sinn Féin leader Gerry Adams in a court case before entering government.
