Daytime show Loose Women is reported to have shed two of its presenters in a bid to boost ratings.

According to Mail Online Kate Thornton – who joined the ITV1 programme in 2009 – and Zoe Tyler, who has been a presenter for four years, will not be returning after the show’s summer break.

There is also speculation that comedienne Sarah Millican may also depart after she said that other professional commitments had left her future on the show in doubt.

Fellow presenter Colleen Nolan announced in March that she would be leaving later this year to focus on other TV projects.

An ITV spokeswoman said, “Kate and Zoe have been fantastic Loose Women. We’ve really enjoyed working with them and look forward to working with them again in the future.”

The show’s other presenters – Lynda Bellingham, Carol McGiffin, Lisa Maxwell, Denise Welch and Andrea McLean – are all expected to return in the autumn.

News of the departures comes amid reports of falling ratings on the lunchtime programme, which began in 1999.

Audiences averaged the 2m mark in January of this year but by June viewing figures had dropped to around the 700,000 mark.
