Five members of a gang behind a string of raids on stately homes - including Britain's biggest ever burglary - have been jailed for up to 11 years each, it can be reported.

The "organised and ruthless" group, all part of the same notorious traveller family, stole priceless antiques which experts estimate could be worth more than £80 million.

A court heard that the gang targeted a number of wealthy homes across Wiltshire, Oxfordshire, Berkshire and Worcestershire where they knew there would be "rich pickings" during a year-long spree.

The men would stake out the country mansions, sometimes for weeks, pinpointing the best means of entry and escape.

Then they would strike - breaking in wearing balaclavas, scouring rooms and escaping in stolen cars within minutes while leaving little or no trace.

Their targets included the Wiltshire mansion of property tycoon Harry Hyams, where they stole property worth millions in a raid described later as the UK's biggest ever private house burglary.

Other victims included Formula One motor racing advertising tycoon Paddy McNally and Lord Lieutenant of Berkshire Sir Philip Wroughton.

Those behind the raids were part of the Johnson family - an organised criminal gang who detectives say have plagued the South of England for 20 years.

Richard "Chad" Johnson, 33, and Daniel O'Loughlin, 32, were both jailed for 11 years, Michael Nicholls, 29, was given 10 years, Albi Johnson, 25, was jailed for nine years and 54-year-old Ricky Johnson was given eight years.

They were all found guilty of conspiracy to commit burglary between April 8, 2005 and October 13, 2006 following a month-long trial at Reading Crown Court.
