Tesco’s UK chief executive, Charles Wilson, is stepping down from the company board after being diagnosed with throat cancer.
Mr Wilson was formerly boss of food wholesaler Booker, but became Tesco’s UK chief following the supermarket’s £3.7bn takeover of Booker in March.
Tesco said Mr Wilson had responded well to treatment and all the signs were that it had been successful.
However, there was a need for him to “remain vigilant in his recuperation”.
Mr Wilson will remain on Tesco’s executive committee and will focus on leading the Booker business.
