The world's largest and grandest ocean liner, the Queen Mary 2, was joined for the first time ever on the River Mersey by fellow fleet members the Queen Victoria and Queen Elizabeth for an unprecedented 'dance' in celebration of Cunard's 175th anniversary.

Although the festivities have been going on for the past three days, the main event took place in Liverpool on Monday with a precision manouevre by the three vessels in front of thousands of spectators.

After their rotation the ships formed a spectacular arrowhead formation, then posed for the cameras before arranging themselves three abreast for the first time in any body of water.

The 'dance' was to culminate with a flyover salute by nine jets from the famous Red Arrows, the Royal Air Force's Aerobatic Team.

The Queen Mary 2 treated onlookers to a magnificent sail-past of the city's historic waterfront earlier this weekend, before tying up at the berth for a little over 24 hours.

During her overnight stay, the 2,600 passengers on board were able to visit Liverpool's sights and experience the energy of the city as the buzz was building ahead of the May 25 event.

And to mark such a significant occasion - the first time that all three Queens have taken to the water together - the Red Arrows are also on hand to complete a series of impressive manoeuvres in their honour.

The world famous acrobatic team followed the Mersey, flying in formation over the three ships in what was one of the most extraordinary spectacles that the city has ever seen.

Cunard Director, Angus Struthers, said: 'The arrival of the Queen May 2 this morning, the largest passenger ship ever to sail up the Mersey, signalled the beginning of Cunard's Salute to Liverpool celebrations in the place where the Cunard story began 175 years ago.'

The entire event has been trending on Twitter and Facebook, with plenty of enthusiasts following along thanks to livestreams and a constant update of photos and the #Cunard175 hashtag.
