In brief: Tax supremo, Riches, moves to Withers

John Riches, a partner in Pinsent Curtis, is leaving the firm to join Withers. He joins the City firm early next month as a partner in the private client department. Riches specialises in tax and trust issues, wealth preservation and succession planning. Murray Hallam, head of Withers' private client practice, said: “John's arrival is a welcome move and demonstrates the continuing importance of London as a centre for private client work.”
