The final series of Big Brother 2018 is currently averaging fewer than a million viewers, based on overnight ratings.
The run launched to a record low audience of 900,000 viewers on Channel 5 last month and Sunday night saw a series low of 575,000 tuning in.
So far, Big Brother's overnight viewing figures have averaged just under 700,000 viewers. This is down around 200,000 on last year's average overnight audience.
In official consolidated numbers - which take into account those watching on catch up in the seven days after an episode airs - the current average across the first two weeks is 1.1 million.
This compares to the 1.2 million series average in 2017, 1.6 million in 2016 and 1.4 million in 2015.
