[bbc] Communication industry regulator Ofcom has not done enough to increase competition among landline providers and to make switching providers easier, an MPs' report has concluded.
The public accounts committee also said Ofcom must do more to allow those that fund it to judge its performance.
It was impossible to determine if Ofcom gives value for money, it said.
Ofcom said it was "surprised" by the criticism about competition, saying that improvements had been made.
However, the report found an "overall positive picture" of competition in the UK communications market.
"The communications market is in most cases working well and consumers are enjoying the benefits of competition," said committee chairman Margaret Hodge.
