Kate and Pippa Middleton - sisters at war

Pippa Middleton's antics have left Kate Middleton distraught

Pippa Middleton's book Celebrate will be released later this year

As pictures of Pippa Middleton cavorting at a party in Paris were splashed across the papers last week, there was a frantic phone call made to the Middleton family home.

 Her sister Katerang mum Carole with one request: that Pippa  be summoned to her parents' Berkshire home immediately  to explain herself.

The Duchess, 30, had a simple question about her 28-year-old sister: 'Doesn't she realise how this affects me?'

Kate's distress was over a series of pictures taken of Pippa during a 48-hour ‘wild weekend' in Paris last week.

First, she shocked everyone  by dressing up as a racy courtier and attending a raucous birthday party complete with burlesque strippers, dwarfs and men wearing dog leads.

The next day she added to the controversy by being pictured smirking in a  car with a male friend holding  a gun, pointed at the paparazzi.

Brandishing a gun in public in France carries a prison sentence for all involved - even Pippa. It's especially insensitive after a spate of recent shootings in the country.

'Kate couldn't quite get her head around the fact Pippa put herself in such a situation,' says  a Royal insider.

'As far as she's concerned Pippa's abused her free rein and, as always, she has  to deal with the consequences.'
