Great Britain’s defence of the BC1/BC2 team Paralympic title came to an abrupt end as they were beaten 18-1 by Thailand in the Boccia semi-finals.

Nigel Murray, Daniel Bentley and David Smith shipped six unanswered points by the halfway mark.

Despite introducing Zoe Robinson into the action, the hosts could do nothing to rein in their runaway opponents.

There was no final place for British brothers Peter and Stephen McGuire either after they lost 3-2 to Brazil.

The brothers, silver medallists at the 2010 world championships, were level at 2-2 in the final six-throw end, but will have to settle for a bronze at best after Eilseu Dos Santos and Jose Pinto Dirceu grabbed a decisive point late on in their BC4 pairs clash.

Boccia is a sport of such fine margins.
