Local MP Alan Mak has voted against Labour's Finance Bill as part of the Conservatives' campaign to stop the Family Farm Tax.
He said that with rising food prices, record farm closures and plummeting farmer confidence, now was the time to support British farmers, not punish them with the Family Farm Tax.
But Labour MPs voted for the Finance Bill, meaning that the Family Farm Tax will now proceed to the next stage of its implementation.
Mr Mak said only the Conservatives were taking the threat to farmers and rural life seriously, and have committed to reversing the Family Farm Tax if it's not scrapped.
He said it had been imposed by a Labour Government that had no understanding of rural life or the importance of family farms.
"Despite Labour previously promising to protect farmers, under Government proposals more than 75 per cent of farms across the country will be hit by new inheritance tax laws.
"They will be devastating for family farms and pose a serious risk to domestic food security and food prices.
"Labour and Keir Starmer do not have a plan to get a grip on the public finances, and are now punishing farmers because of their failures."
Mr Mak, who will continue to campaign to get Labour to scrap the Family Farm Tax, added: "Labour must u-turn. I'm sure people in the Havant Constituency and across the country will never forgive them if they destroy the farming industry, as this tax will ultimately do."
