Labour leader Sir Keir Starmer left politics at the turnstiles to join former shadow chancellor Ed Balls at a Championship match.
Sir Keir - an Arsenal fan - was spotted in the directors' box at Carrow Road as Norwich City took on Sunderland.
Mr Balls, a lifelong Canaries' fan, is vice-president of the club and watched his team win with the game's only goal.
Labour's website says Sir Keir is "obsessed with football" and has a season ticket at the Emirates.
He was able to attend the game as Arsenal play Sheffield United on Monday night at Bramall Lane.
