"NAV per share is up to 419 pence per share and proposed interim dividend is 9 pence per share," he said in a statement.
"We have not seen a negative impact from Brexit on our portfolio, which appears to be a London-focused issue, in fact we have seen increased activity in the towns and cities in which we operate.
"We are making headway on several of our strategic assets and with our policy of sourcing opportunities both directly and corporately, I continue to be very optimistic about our future."
