Thousands of BBC journalists began a 48-hour strike over pensions on Friday, knocking some of the broadcaster's flagship shows off air.
The walkout by around 4,000 members of the National Union of Journalists which began at midnight London time caused significant disruption, with television and radio shows enjoyed by millions pulled entirely or cut back.
BBC Radio Four's flagship current affairs programme, "Today", which has about 6.5 million listeners each morning, did not go out Friday, replaced instead by a series of pre-recorded shows.
