An independent investigation is to examine the Electoral Commission's decision to allow an extremist party to use a slogan featuring murdered soldier Lee Rigby.
Jenny Watson, chair of the independent commission, said today that "an immediate and full independent investigation" will follow to "prevent this from ever happening again".
The watchdog issued an apology yesterday for allowing Britain First to use the description "Remember Lee Rigby" on voting slips for next month's European elections.
