Plans to reform the House of Lords in Britain are in disarray after the government was forced to abandon a vote on the reforms.
A significant minority of Conservative MPs said they would rebel and vote against the plans.
The BBC reports the bill would establish a largely elected House of Lords.
However, the government later won a separate vote on the principle behind a mainly elected chamber with a majority of 338. But 91 Conservative MPs voted against the bill as a whole.
The vote means that proposals for an 80% elected House of Lords that is half its current size will proceed to their next stage of parliamentary scrutiny in the autumn.
Commons leader Sir George Young said the vote would be postponed until after the summer recess.
However, abandoning the vote is likely to increase tensions within the coalition.
