Twenty victims of the Paddington rail disaster still have outstanding compensation claims to be settled, according to a report.
St Paul International insurance, the insurer handling the claims has reached its pre-determined pay-out limit and has transferred the outstanding cases to its excess layer insurer, AIG.
According to a report, AIG has appointed solicitors conduct a review of the outstanding claims, building on the oustanding files St Paul forwarded to them.
The claims are believed to involve sums ranging from £300,000 to several million and, according to the report, concern survivors of the disaster and relatives of those killed.
A spokesman for St Paul said the company was entirely confident as the primary insurer that it had dealt with the claims as sympathetically and quickly as possible.
He added the vast majority of claims had already been settled, with those still outstanding being the most complex cases which would inevitably take longer to resolve.
It is four years since the rail disaster left 31 dead and more than 400 people injured.
