Next week could be MPs' "only opportunity" to challenge a no-deal Brexit, ex-minister David Gauke has said, APA reports citing BBC.
This follows the prime minister's decision to suspend Parliament in September and October.
A statement from opposition parties accused the PM of shutting down Parliament with "the sole aim" of stopping MPs from preventing a no deal.
Leader of the House Jacob Rees-Mogg said outrage at the plan was "phoney".
The government said the five-week suspension - known as prorogation - in September and October will still allow time to debate Brexit.
But government whip Lord Young has resigned in protest, arguing the move risks "undermining the fundamental role of Parliament".
And a Scottish court hearing is under way which could block the suspension of Parliament.
