Dominic Cummings, Prime Minister Boris Johnson's senior adviser, said on Thursday the current Brexit maelstrom was a "walk in the park" compared to the 2016 EU referendum, saying there was no pressure and they were enjoying it, the Daily Telegraph said.

Cummings played a key role in masterminding the leave camp to victory in the vote three years ago and joined Johnson's staff after he took office in July since when the already chaotic Brexit process has become even more confused.

Johnson has vowed that Britain will leave the European Union on Oct. 31 with or without a divorce deal, but Parliament has passed a law to compel him to seek an extension if he has not gotten an agreement by Oct. 19.
