Reform’s Scotland leader was hit by an online backlash after providing details of his assets during a live TV Holyrood election debate on Tuesday evening.
Cross-examining Mr Greer during a head-to-head segment, Lord Offord said: “Today, I own six houses, five cars and six boats. In a 40-year business career, I’ve employed thousands of people and paid £45m in tax.
“I don’t say this to boast – but to ask you this question: Mr Greer, in your Scotland, do you want more people like me, or fewer people like me?”
The Greens’ co-leader, who has proposed a series of radical tax increases on wealthier Scots, responded: “Fewer people like you. I’m glad you finally admitted how many homes you have.”
John Swinney, the SNP leader and First Minister, said that the peer’s comments were “tone deaf” at a time when families were struggling to make ends meet.
However, an unrepentant Lord Offord said Scotland was “the only country that does not seem to admire wealth” and he wanted to make it richer.
Speaking before next week’s Holyrood election, he said he had been transparent about “who I am, what I am, and it’s up to the Scottish people to decide whether they like that or not”.
The former Tory party donor – who defected to Reform UK in December – has previously refused to answer questions on his net worth.
After leaving university, Lord Offord became a banker in London. He went on to found the investment firm Badenoch and Co and was given a life peerage by Boris Johnson in 2021.
Unveiling his plan for an “Offord tax”, Mr Greer said: “Nobody needs six houses, and it is baffling that Lord Offord thought that it was something to boast about, along with all of his yachts and cars.
“Housing is a human right, but a small number of very rich people like Lord Offord are hoarding homes they just do not need. At the same time, thousands of people can’t get a home of their own and are being priced out of the communities they grew up in.
“The Scottish Greens’ Offord tax will help to tackle that imbalance. By making it more expensive for those who already own their own homes to hoard extra properties, we can boost the chances of first-time buyers having their offers accepted.”
But Thomas Kerr, a Reform councillor and election candidate in Glasgow, said: “Grow up, Mr Greer. If the Greens were even remotely serious about tackling Scotland’s housing crisis they’d make it easier to build homes rather than indulging in childish gimmicks.
“Reform UK have been clear. We want Scotland to be the wealthiest nation in the UK. That means more Malcolm Offords and less Ross Greers.”
Second home owners in Scotland are already facing 500pc increases in their council tax premiums after local authorities were handed powers to raise bills by uncapped amounts.
The Scottish Government has pledged to introduce a “mansion tax” on properties worth more than £1m by April 2028. Rachel Reeves, the Chancellor, has announced a similar tax for properties in England worth more than £2m.
