The UK's private equity dealmakers enjoyed their busiest summer in five years as ongoing political uncertainty over Brexit failed to dampen appetite for buyouts in the country.

Buyout and growth firms completed 65 investments in UK companies from July 1 through to September 30, according to Dealogic — a near 14% increase on the 56 deals in the same period last year and the joint-highest figure for any quarter since 2013 alongside Q2 in 2014.
