Programmes including BBC One's Breakfast and Radio 4's Today programme are off-air this morning due to a strike by BBC journalists.
Radio 5 Live Breakfast presenter Nicky Campbell was also absent as shows were affected by a 24-hour walkout by members of the National Union of Journalists in protest at compulsory redundancies.
Repeats of shows including Heir Hunters and Escape to the Country will replace BBC One's Breakfast.
