David Cameron has appointed Boris Johnson's brother Jo as his head of a new Conservative parliamentary policy advisory board in a re-organisation of the party's political operation. Mr Johnson was elected as MP for Orpington, in Kent, in 2010.
The Daily Telegraph's political correspondent Peter Dominiczak has tweeted London Mayor Boris Johnson's reaction to his brother Jo heading up a Policy Unit in Downing Street.
Boris and Jo Johnson share the family's trademark ultra competitiveness, but in many ways they are very different people.
Jo Johnson will head up the Policy Unit inside Downing Street in a shake-up to inject fresh Tory thinking into Government.
