Mr Campbell-Savours had the whip removed by Chief Whip Jonathan Reynolds after voting against the measures, citing “deep concerns” about their impact on family farms.
Dozens of other Labour MPs abstained from the Commons vote, following a call from the National Farming Union (NFU) for them to show support for working people in the countryside.
Backbenchers argued that most farmers are not wealthy and that the changes would devastate elderly farmers, while failing to tackle tax avoidance by celebrities and billionaires.
Despite the opposition, MPs voted in support of the government’s plans by 327 votes to 182, with a Treasury minister defending the changes as a “fair way forward”.
