A quick google reveals that the Grey Friars in Leicester had a politically interesting history:
"The sympathies of the Leicester Franciscans for Richard II brought serious consequences upon the friary in 1402. A Franciscan declared to Henry IV that he and ten other friars of the house at Leicester, together with a master of divinity, had conspired in favour of the deposed Richard. In consequence eight Franciscans of Leicester, with the master of divinity, were arrested and brought to London for trial. The remaining two friars escaped. After two juries had failed to convict, a third jury found the prisoners guilty, and they were executed. Two other Franciscans from Leicester, presumably the two who had at first escaped, were executed at Lichfield about the same time. (fn. 9) In 1402, at a general chapter of the Franciscans held at Leicester, it was forbidden to any of the Order to speak against the king."
