Overseas owners sold eight UK companies in deals worth a combined £6.9bn over the first quarter of this year – the highest value on record.
Yet overseas buyers continued to push money into the UK during the first quarter of this year, as they acquired UK businesses in 75 transactions worth £21.7bn.

Tesco's Booker deal helped to lift the total value, as did Montagu Private Equity's play for tech firm Servelec.
