Prince Harry reportedly snuck Meghan Markle into his £1 400 (R25 403)-a-night Toronto hotel suite following their appearance at the Invictus Games.

The loved-up couple made their first official public appearance together at the sporting event in Canada, and the duo subsequently retreated to a luxurious Royal Suite, which features a fireplace, a bar, and 16-seater dining room, according to the Daily Mail newspaper.

Their spectacular room cost as much as £1,400 per night, although a slightly smaller room was available for £1 160 (R21 055).

Prince Harry and Meghan's appearance in Canada comes amid intense speculation that the duo are preparing to tie the knot, with a source recently saying that they are "heading in [the] direction" of an engagement.

The high-profile couple have been dating since mid-2016 and while rumours of an imminent engagement are said to be premature, their relationship has been progressing serenely in recent times.

A source explained: "Harry and Meghan are not engaged yet, reports that they are are jumping the gun slightly. 

"They are definitely heading in that direction, but when they do get engaged Harry will follow Royal protocol and an announcement will be made by the Palace."

Prince Harry and the 'Suits' actress are said to be very much in "love" with each other, but neither of them wishes to commit to marriage before they're totally ready.

The insider added: "Harry and Meghan are very much in love, but they both want to make completely sure that they are ready to take the next step before doing so. 

"Harry does not want to make the same mistake as his mother and father did. When he marries it will be for life, and it's not something he is going to rush into."
