Prince Harry jokes on the phone at charity event days after Meghan Markle was seen wearing necklace with his initials

PRINCE Harry cracked jokes on the phone as he brokered multi-million pound deals on a City trading floor today.

The Prince visited global firm ICAP after touching down in London following a whirlwind visit to Canada to see girlfriend Meghan Markle at the weekend.

Surrounded by staff wearing fancy dress, Harry joked to one caller: “I’m not entirely sure what country we’re in,” – perhaps unsurprising, given his 1,700 mile detour on the way back from his Caribbean Tour, which saw him visit seven islands in two weeks.

As he moved around the desks and was given help with trading, Harry told staff: “There’s no point in explaining to me – I’ve no idea.”

But he soon seemed to get into the swing of things – at one point urging a caller to “stop making small talk”, and telling another: “We’d like a bit more than that please,” before sealing a deal worth over £503million.

Meanwhile, closing a deal with Bank of Ireland, the Prince signed off his call saying: “Open up a Guinness and have a good day.”

On his way out, Harry praised the staff  – who were marking their annual charity day, which has raised almost £127million since 1993.

He said: “Everyone’s made so much effort this year.”

Meanwhile, as Harry returned to the UK, girlfriend Meghan Markle was spotted flaunting a delicate gold chain featuring the loved-up pair’s initials.

The smitten Suits actress showed off her new piece of jewellery as she shopped for flowers in Toronto at the weekend.

The pretty necklace had two tiny letters, a H and a M, hanging off it and is thought have been made by Los Angeles designer Maya Brenner.
