New Delhi, July 26 - In an apparent reference to Uttar Pradesh party chief Rita Bahuguna Joshi's remarks against Chief Minister Mayawati, Congress president Sonia Gandhi has urged party workers never to lose 'mutual respect' for political leaders and ideologies and always observe 'diplomacy and decorum'.

In an editorial in the latest issue of party mouthpiece Sandesh, Gandhi has asked partymen to 'inculcate the habit of diplomacy and decorum in expressing our anguish whenever required'.

'Lately it has been seen that political leaders have become prone to using intemperate language while reacting to political situations,' Gandhi writes.

'Mutual respect for political leaders and ideologies must never be lost,' she has added.
