The BBC risks undermining Brexit and damaging the UK's reputation with its "pessimistic and skewed" coverage, MPs have warned.

More than 70 MPs from across the political spectrum have written to Lord Hall, the director-general of the BBC, accusing the corporation of portraying the UK as a "xenophobic" nation that regrets the vote to leave the EU.

They say that the corporation has failed to "break out of pre-referendum pessimism" and accept the "economic good news" the UK has enjoyed since the referendum.

The letter comes after months of mounting anger in the Conservative Party about the corporation's coverage of Brexit in the wake of the EU referendum.
