Chris Moncrieff, a political reporter who covered Westminster for more 50 years for the Press Association (PA) agency, has died aged 88.
The journalist, who continued to file stories after officially retiring in 1994, was described by PA's editor-in-chief Pete Clifton as a "legend".
In 2007, the House of Commons press bar was renamed in Mr Moncrieff's honour.
Former Prime Minister Tony Blair once described him as "the only journalist who mattered".
Mr Moncrieff, who had four children with his late wife, Margaret, joined PA's parliamentary staff in 1962, before becoming a lobby reporter in 1973.
