Jeremy Corbyn addressed a crowd of hundreds at a protest event in Manchester during the Conservative Party conference.
Leaders of the main parties traditionally stay away from rivals' conferences, but Mr Corbyn appeared at a public meeting organised by the Communication Workers' Union.
The Labour leader's visit to Manchester comes after tens of thousands of activists marched through the city centre to protest about Government policies on the conference's opening day.
Although the march, involving an estimated 60,000 people, was largely peaceful, there were some ugly scenes and four arrests.
Mr Corbyn had appealed for activists to "focus on policy and take no part in personal attacks".
