ITV marked its 70th anniversary on Monday with a star-studded gala at London's historic Guildhall, where presenters, actors and journalists from across the broadcaster's output gathered to celebrate seven decades of television.

The evening, hosted by Joel Dommett, returned to the site of ITV's inaugural transmission in 1955 and honoured landmark moments from news, drama, daytime and entertainment programming. Cat Deeley and Olivia Attwood, both regulars on ITV daytime output, were among those photographed arriving for the event.

Cat Deeley, 48, who announced her separation from husband Patrick Kielty earlier this year, attended the celebration wearing a bright orange long-sleeved minidress and posed with fellow This Morning presenter Ben Shephard. Olivia Attwood, 34, who recently joined the This Morning presenting team after rising to prominence on Love Island, arrived in a white oversized blazer over a crop top and wide-leg trousers.

The guest list spanned ITV's current slate and its long-running dramas. Good Morning Britain presenter Susanna Reid arrived in a black evening gown, while co-presenter Charlotte Hawkins wore an embroidered blue sheer dress. Kate Garraway, Lorraine Kelly and Gloria Hunniford were also photographed on the red carpet. Graham Norton attended in a grey velvet suit, and former Love Island host Laura Whitmore was accompanied by her husband, comedian Iain Stirling.

Soap actors representing both Coronation Street and Emmerdale were present, including Ben Price, Barbara Knox and Channique Sterling-Brown from Coronation Street and Charlotte Bellamy, Zoe Henry, Lisa Riley and Natalie J. Robb from Emmerdale. Cold Feet actress Fay Ripley and Emmerdale veteran Claire King were also among attendees. Anne Hegerty, known for her appearances on The Chase and I'm A Celebrity, and Paralympic champion Ellie Simmonds were photographed arriving.

The anniversary comes amid recent announcements of cost-saving changes to ITV's daytime schedule. Reports earlier this year said the channel planned cuts affecting programmes including Lorraine and Loose Women, with Lorraine reduced to a 30-minute daily slot and both shows set to move from their Television Centre studios to smaller facilities. ITV did not announce any programming changes at the Guildhall event.

ITV last marked a milestone at the Guildhall for its 50th anniversary in 2005. The 70th-anniversary evening aimed to showcase the broadcaster's longevity and the breadth of its programming, drawing talent from newsrooms, studio sets and scripted series to celebrate the network's place in British television history.
