WHO DO YOU THINK YOU ARE?, 9PM, BBC1

OVER the past few years, former model Emma Willis, 41, has presented some of the most popular shows on British TV, including The Voice and Celebrity Big Brother (a new series of which began on Ch5 on Tuesday). After beginning her ancestral investigations in her much-loved home town of Birmingham, it’s not long before Emma (pictured) is on the trail of relatives in Ireland, where, after being confronted by unsettling news about one less than savoury character, she’s grateful to find herself digging up a more positive story for the family archive.
