The prime minister said lobbying proposals would be introduced "within the next month" and claimed his government has done more in 18 months than the last one had done in 13 years.

During PMQs, Labour's John Cryer had offered the PM his own 10-minute rule bill after he claimed the government had done nothing so far.
