Jamie Stone has criticised Prime Minister Boris Johnson's plans to suspend the House of Commons in order to force through a no-deal Brexit.
Mr Stone, the Liberal Democrat MP for Caithness, Sutherland and Easter Ross, called the move "dangerous" and "irresponsible".
He said: "This is an outrageous decision by a Government claiming to be 'taking back control'.
"Just yesterday almost 200 MPs, including myself, signed the Church House Declaration which said shutting down parliament would be 'an undemocratic outrage at such a crucial moment for our country, and a historic constitutional crisis'.
"And yet the Government is ignoring parliament and trying to force through a no-deal Brexit, which the majority of MPs are against.
"Westminster is considered the cradle of democracy, but Johnson is treating it with contempt. This is a deeply dangerous and irresponsible way to govern.
"My constituents elected me to represent them and this means stopping a no-deal Brexit which will be extremely damaging to the Highlands, Scotland and the whole UK.
"The Liberal Democrats demand better and we will continue to oppose any attempts to shut down parliament."
