Diane Abbott swears oath of allegiance to the Queen

Firebrand goes down on one knee and kisses ring

DIANE ABBOTT reportedly hurled a four- letter insult at Cabinet minister David Davis when he tried to give her a kiss after she voted for his Brexit Bill.

The hard-Left radical has, however, accepted the warm embrace of the Establishment.

For I can reveal that Abbott, 63, who once co-authored a pamphlet calling for the ‘dismantling’ of the monarchy, went down on one knee in front of the monarch at Buckingham Palace this week.

She kissed the Queen’s ring before swearing the oath of allegiance as part of the ceremony in which she became a member of the Privy Council. Abbott (pictured) was invited to join the body, which advises the Queen, because of her role on the Labour frontbench — a job handed to her by the party’s Loony Left leader, Jeremy Corbyn, her former lover.

A Buckingham Palace spokesman declines to comment on the ceremony, which took place on Wednesday, but a fellow Privy Counsellor, who was present, confirms that Abbott took part in the traditional ceremony for new members.

A spokesman for Abbott tells me: ‘Diane was sworn in, but she’s been advised not to talk about the procedure and exactly what happened.’

The MP, who provoked an outcry when she failed to turn up for one of the votes over the Brexit Bill —

claiming to have been suddenly taken ill — will now be allowed to style herself as ‘Right Honourable’. Her new status will permit her, as shadow Home secretary, to be briefed on state secrets.

Also sworn in was shadow foreign secretary Emily Thornberry. The feminist recently complained formally to the House of Commons speaker after Theresa May referred to her as Lady Nugee (her husband is High Court judge sir Christopher Nugee).

Thornberry was, though, also prepared to accept tradition by going on bended knee before the Queen and swearing the oath of allegiance.

There was controversy in 2015 when Buckingham Palace made allowances so that Corbyn, an anti-Monarchist, could join the Privy Council but not have to kneel before the Queen.

He was accused of snubbing the Monarch by refusing to be sworn into the Council by going on a short break to scotland rather than meeting Her Majesty for the ceremony. He finally joined weeks later.
