LONDON, July 28 (Reuters) - Britain's ITV said advertising had rebounded strongly, with June delivering the largest ad revenue for the month for the broadcaster in its history as it benefited from the easing of COVID-19 restrictions and the Euros.

The company, which broadcast England's semi-final victory over Denmark in Euro 2020 to a peak of 27.6 million people this month, said its total external revenue for the first half rose 27% to 1.55 billion pounds ($2.15 billion).
