The Ukrainian opposition may decide to surrender mandates.

"The decision is quite possible because we can have only way out of this situation - not to enter parliament and thus not let it assume its powers," United Opposition candidate Viacheslav Kyrylenko said on Channel 5 on Sunday.

"This is one of the many decisions that can be made in protest against the abuses," he said.

He said the decision may be announced at the opposition action at the Central Elections Commission at 1000 on Monday.
