Kumar, who was under pressure from his party to resign his ministership or heed to party directives, today said he would work for unity in the party headed by his father.
His reaction came after Pillai, who had been at loggerheads with his son for long for his 'one-man show' defying the party, warned him after a party meeting this morning that he could continue in office only if he went by party directives.
"My father and I will work together," he said, ending a prolonged fight between the two.
The turnaround came after Kumar recently got embroiled in a row over an alleged extra-marital relationship,reported by a newspaper without naming him. Government Chief Whip and Kerala Congress-M leader P C George later alleged that Kumar was the person mentioned in the report, kicking up a row.
The truce in KC-B also comes as a relief to Congress-led UDF, which is in power with a wafer-thin majority.
