MP Drew Hendry has urged the boss of the Royal Bank of Scotland (RBS) to meet him face to face to discuss branch closure plans.
Speaking outside the Nairn branch during a protest last Saturday, he described the policy as unacceptable.
"There’s been no consultation with the communities and the people who’ve tried to find out what alternative services there would be have found there is no information is available," he said.
RBS previously announced plans to close 62 branches across Scotland, citing falling customer demand.
While 10 of these were later given a stay of execution the Nairn branch remains scheduled to close.
Reminding the bank that it is largely owned by the UK Treasury, Mr Hendry said: "RBS chief executive Ross McEwan needs to be hauled in and told that this needs to be stopped until there is a proper discussion with communities about the future of banking."
RBS maintains that customers increasingly choose to do their everyday banking online or by mobile phone.
Since 2012, it said, the number of customers using its branches in Scotland has slipped by 44 percent.
