He won at Aintree on the aptly-named Party Politics just two days after the General Election in 1992.
And Llewellyn was back in the winner's enclosure at Liverpool six years later aboard Earth Summit - the last favourite to win the race.
On both occasions he had stepped in for an injured jockey - Andy Adams and Tom Jenks respectively.
If further proof is needed of Llewellyn's National credentials, look no further than the 1997 renewal when he steered 100-1 outsider Camelot Knight into third place.
Two years ago, on the heavily-fancied Beau, Llewellyn was in with a great chance of a third National win.
He recovered from finding himself with the reins over his mount's face, only to be unseated at the 20th.
The Welshman even tried to chase down the eight-year-old and remount, but his efforts were to no avail.
Last year it is fair to say another winning opportunity passed Llewellyn by when he opted to partner Beau instead of Bindaree - stablemates in the Twiston-Davies yard.
It is the only race Bindaree - last year's National winner - has run without the Welshman in the saddle.
Away from Aintree, Llewellyn enjoyed his greatest success in partnership with Beau at the Whitbread Gold Cup.
The pair won the Sandown event in 2000 by the biggest winning margin in the race's history.
