Scott Morrison had passed along an unusual gift for the Queen while stopping off at London for his special trip.

The Australian Prime Minister had been invited to Buckingham Palace in an intimate meeting just a day after US President Donald Trump made headlines internationally for his state visit with the 93-year-old monarch.

The 51-year-old was pictured holding a red gift bag upon meeting with Her Majesty alongside his wife, Jenny.

The unusual gift was revealed to be a copy of Winx: Greatest of All Racehorses which had been signed by author Andrew Rule.

What makes this unique gift all the more special is the simple fact Queen Elizabeth is an avid horse fan.

While Winx is retired, the Australian racehorse has long been an iconic figure after his historic four-year run of 33 consecutive race wins.

Both Mr Morrison and his wife also met with Prince Charles and Duchess Camilla at Clarence House before visiting the Queen.

The UK is just one stop of many for the PM who announced after his election win last month that he would be re-engaging with Australia’s neighbours, partners and allies across the globe.

For his first stop, Mr Morrison visited the Solomon Islands, a place he described as “one of Australia’s nearest and most important neighbours".

He was the first Australian leader since 2008.

“Australia and the world face uncertain times and global economic headwinds,” the PM said. “Our engagement with our family and neighbours and international partners is more important than ever.”

Later this week, Mr Morrison will visit Singapore to highlight Australia’s commitment to enriching economic and security ties with Southeast Asia.
