POGS, in response to your post @ 00:07 today (10/03/19), the reason the complaints regarding anti-Semitism are higher among Labour MPs than complaints in regard to Islamophobia among Conservative MPs would be that there are a number on the Labour benches that have never accepted the election of Jeremy Corbyn as leader.
In that, anti-semitism has been used to undermine the Corbyn leadership and obstruct the clearly demonstrated democratic will of the of the Labour movement membership. Evidence to the foregoing can be witnessed in the actions of Margaret Hodge.
In the above, I believe that Hodge has submitted over two hundred anti-semitism complaints in her own name to the General Secretaries office which is obviously designed to overwhelm the system at the expense of the Corbyn leadership she is without doubt hoping. However, many are wondering how Hodge found the time to "thoroughly check out" all that number as anything like genuine before forwarding them to Jenney Formby's office.
In addition to the above, we now have the Hodge covert recording of the meeting she held with Jeremy Corbyn to discuss all those complaints. In that, words fail many in regard to the Hodge behaviour.
However, in the Tory party despite having had Fourteen counsellors and other senior members suspended or resign in recent weeks over their islamophobic actions, according to the leadership of the party there is still no problem, therefore no inquiry is necessary.
There is also evidence of Islamophobia having been rife in the Conservative Party for a considerable amount of time and at the very top of its structure. There was the invite by Tory MP Bob Blackman to Extremist Hindu preacher Tapan Ghosh to speak on his well-demonstrated Islamophobia within the Westminster parliament estate in 2017. However, no action was taken against Blackman, as the Chairman's office felt there was "no problem" with the preacher's invitation.
As the old adage states, "there is none so blind as those that do not wish to see."
