Savills, one of the countries largest estate agents, said that 55 per cent of all properties in London worth more than £750,000 that it sold were bought by foreigners this year, compared with 45 per when the housing market hit its peak during 2007.
Though large houses and upmarket flats have often been bought by foreigners in London, this is the first time that an estate agent has said that more than half its clients are from overseas.

How do we know they aren't foreign Welsh, Scots etc?
