Smitten Boris Johnson gets on his bike after leaving girlfriend Carrie Symonds’ house

LOVE-struck Boris Johnson gets on his bike after spending the night at girlfriend Carrie Symonds’ house.

The ex-Foreign Secretary was seen leaving on Thursday — four days after Carrie was pictured tweaking his bottom as they arrived at her London pad.

Mr Johnson, 54, headed off just after 7am for a conference in Dublin, while Carrie, 30, emerged four hours later.

She was later seen getting into a cab sporting a bright-patterned floral dress.

The Sun told on Saturday how smitten BoJo plans to marry his lover as soon as the ink is dry on his divorce from wife of 25 years Marina Wheeler, 54.

Carrie, who works in PR at financial firm Bloomberg, is five years older than the politician’s oldest daughter — but has yet to meet his children.

Dad-of-four Boris is said to have fallen head-over-heels for her. And a pal told The Sun: “He wants to get engaged. He’s completely in thrall to Carrie. Totally loved-up. It’s quite sweet.

“He’s like a puppy dog around her and very solicitous, but desperate to avoid messing it up.”

Boris divorced first wife Allegra Mostyn-Owen in 1993 while Marina was pregnant with their child.

They married eight days later, but split for good last August.

We told how the pair were living apart and no longer socialised as a couple.

At the time, fashion journalist Lara is understood to have exploded with rage, telling pals her dad was “a selfish b*****d”.

She told one friend: “Mum is finished with him.

“She will never take him back now." The couple’s marriage had previously been rocked by a number of flings Boris had enjoyed with other women.
