The number of high-end London homes being placed on the market has dropped by a quarter as wealthy owners hold off selling ahead of the UK’s departure from the EU.

In upmarket areas of the capital, the number of homes being placed on the market for ￡2m or more was down 25 per cent in the third quarter of 2018 compared to a year before. For all homes in those markets, the drop was 19 per cent, according to LonRes, a property data group.
