The owner of Wagamama is facing pressure from shareholders to split itself up.
Its embattled management team are expected to be questioned about pay and performance at its annual general meeting this week.
TMR Capital has become the latest investor to call for an overhaul of the Restaurant Group, after taking a small stake this month. It is believed to want TRG, which also owns Brunning & Price, Frankie & Benny’s and Chiquito, to sell all its businesses except Wagamama.
