The Culture, Media and Sport select committee said up to 40 per cent of tickets were being sold on the internet.
While the committee's report stops short of calling for a total ban on resale, it tells online touts to "clean up their act" and calls for a voluntary industry code of conduct for reselling. It also criticises event organisers and promoters for helping to feed the market with non-existent or inadequate returns services.
Committee chairman John Whittingdale said it was "neither practical nor in the interests of consumers" to ban ticket sales through the secondary market - where tickets are sold on.
Dozens of UK venues and promoters gave evidence to MPs for the report, which concludes that "some secondary sellers indulged in dubious or suspect practices".
