Bajwa also rejected an Akali leader's claim that according to the Sikh religious code of conduct, Sikh women are not allowed to perform ‘Kirtan’ at the ‘Darbar Sahib and mentioned,

There was no mention in the Sikh history of any discrimination against women. But Sikh women were not allowed to perform Kirtan Sewa till now. Only Sikh men perform ‘Kirtan’ at the Golden Temple currently.
