Concerns over Russian attempts to meddle in elections are reverberating across the Atlantic.
British lawmakers asked Twitter on Friday to provide a list of accounts that are associated with a Russian government-linked troll farm known as the Internet Research Agency.
Damian Collins, chair of the Digital, Culture, Media and Sport Select Committee, said that some of the accounts, which were the focus of congressional hearings this week in the United States, were also posting content related to British politics.
“Any interference by foreign actors in the democratic process of the U.K. is clearly a serious matter,” Collins wrote in a letter to Twitter CEO Jack Dorsey. He asked the social media firm to provide the information before the end of the month.

Many of the same issues are now being raised in Britain.
In October, Collins asked Facebook to provide information on any ads purchased by Russian-linked Facebook accounts.
He also told CNNMoney that he would consider holding a committee meeting on the issue at the British Embassy in Washington, D.C., so that major U.S. tech executives could be questioned.

Another U.K. parliamentary group — the Public Administration and Constitutional Affairs Committee — said in a report earlier this year that while it had no evidence of meddling in U.K. elections, it was “deeply concerned about allegations about foreign interference.”
