A British expat has revealed how a spiralling legal dispute with a neighbour over a driveway led to him losing almost his entire retirement fund including homes worth £1.5million pounds - and culminated in him being thrown in a Thai jail.

Martin Savage, 65, looked forward to a dream retirement when he relocated to Thailand with his dual Thai/British citizen wife Sudarat, 66, but a boundary dispute with a neighbour saw legal fees eat up his credit.

And when Sudarat used his Thai property assets to underwrite his legal battle, he ended up in breach of Thai property law which saw him and Sudarat both sent to prison.

The retired engineer - whose successful career saw him work on major construction projects like the Channel Tunnel - has gone from a peak annual retirement income of £38,000 to struggling to live on just £100 a month from the tiny private pension which is his only surviving asset.

Speaking out to warn others of the dangers of retiring overseas, Mr Savage said last night: 'I have lost everything, I'm completely broke.'
