Staff at stricken electricals chain Comet are urging ministers to investigate its collapse and former owners OpCapita.

Angry workers have launched an online petition urging Parliament to look into the way the private equity firm ran Comet, which collapsed into administration earlier this month.

More than 1100 people have signed the petition, which wants OpCapita and its boss Henry Jackson to be questioned over money invested in the firm.

Comet's administration comes just months after the investment firm bought the chain for a nominal £2 in February. The retailer employs 700 staff in Scotland.

The petition says: "The promise was made that OpCapita would turn our fortunes around. Yet all that's happened is that we've been stripped down until the company wasn't self-sustainable any more."

OpCapita was not immediately available for comment.
