Home Affairs Committee Chairman Keith Vaz said there were several major issues to ask May about, "including police reform (and) the difficulties in deporting of foreign terrorists."
Last month, radical Islamic preacher Abu Qatada won an appeal against deportation to Jordan, where he's wanted on terrorism related offenses. The Daily Mail newspaper in London reported in September that suspected foreign terrorists were able to avoid deportation by using human rights laws. Some claimed they'd be mistreated if deported.
May has long sought the deportation of Qatada, who had spoke in favor of the 2001 al-Qaida attacks on the United States.
Last week, the British Home Office said the number of people arrested on terrorism charges in England, Wales and Scotland for the year ending June 30 increased 61 percent to 228 compared to the same period the previous year. A total of 49 people were charged for a terrorism-related offense.
