Most memorable housemates to return

The most memorable housemates from the last nine years will re-enter the Big Brother house, it has been revealed.

From Sunday, a week of celebrations to mark the tenth anniversary of the show will get underway.

Each day, a former housemate will go up against a member of the current group in one of the most talked-about tasks from the programme's history.

Producers of the series have also advised viewers to expect some other surprises in the live broadcast taking place on Friday, July 17.

Meanwhile, The Sun recently reported that Nikki Grahame from Big Brother 7 will be the first ex-housemate to undertake a challenge.
