impartiality

"The SNP and Plaid Cymru are appealing against a decision by the BBC not to include their leaders in a televised UK general election debate.

Alex Salmond and Ieuan Wyn Jones have written to the BBC Trust to request an oral hearing to appeal against the BBC executive's decision.

The pair are angry their parties will not be represented in three debates to be televised on the BBC, ITV and Sky.

The BBC argues it has clearly set out how impartiality will be achieved.

The BBC Trust said it could not comment in advance of receiving the letter."
