Families should only be able to watch one video at a time on their smart-phones, tablets and computers under Government plans for "minimum" broadband speeds, BT has suggested.

The telecoms giant has revealed in response to a consultation that it is resisting the Government's plans to give every family in the UK a legal right to fast internet connections.

It has questioned whether households should expect their broadband to be fast enough for them to to watch "multiple video streams" at the same time or view films at the "highest quality" available, suggesting that most households in Britain only use a single device at a time.
