Fortnum & Mason has apologised for a “failure of communication” to Paralympians who were not invited to a party which Olympians attended, after the Paris medallists met the king at Buckingham Palace.

Team GB and ParalympicsGB athletes were hosted at a reception at the royal residence on Thursday 7 November to celebrate Britain’s success this summer.

Three members of the British para-cycling track team were robbed of their silver medals and other possessions in a mugging after the opening day of the world championships in Rio de Janeiro.

Lora and Neil Fachie, who are both double Paralympic champions, and pilot Corinne Hall were left shaken but otherwise unharmed by the incident, which occurred as they made their way back to their accommodation in the Brazilian city.

British Paralympic officials say they were left stunned when hotels near their training camp for the 2020 Games demanded they pay to make rooms accessible for wheelchair athletes – and then pay again to convert them back afterwards.

One senior figure said there had been a “total lack of interest” from hotels they had contacted in Yokohama when it came to helping the British Paralympic team, who will make their final preparations in the city ahead of Tokyo 2020. Another source said the issue had been a “huge headache” for more than 18 months.
