Duncan Mitchell-Innes, of law firm TWM Solicitors, said: “With many people expecting a rise in capital gains tax, there has been a surge in sales of assets in recent weeks.”
HM Revenue & Customs benefited from record CGT receipts in August as swathes of landlords and investors sold up, according to figures published last week.
In total, £197m of CGT was paid last month, the highest level for August since at least 2008.
The share sale by Lord Wolfson marks the third time he has done so to bring his holding down to around £100m worth of shares.
It follows a share price rally at Next with its stock surging by 123pc since October 2022.
Next’s share price has been boosted by a string of upgrades to its profit forecasts, as the retailer has fared better than rivals during the cost of living crisis.
Earlier this month, Next said it was expecting full-year profits to come in £15m higher than its previous forecasts. Pre-tax profits are set to come in just under £1bn, it suggested, buoyed by stronger sales overseas.
Next said the rise followed a “convergence” of international fashion tastes, with more people watching streaming services such as Netflix, Amazon Prime and TikTok. It said this was encouraging customers to try clothes that were popular in other countries.
